Selection- weighted attraction graphing (SWAG) uses force-directed network graphing to visualize fitness landscapes. In this visualization, genotypes are represented by nodes which are attracted to each other in proportion to the relative change in fitness between them (nodes will tend to be closer if there is stronger selection strength between them on average). Additionally, fitness values may be assigned to the z-axis to create an empirical three-dimensional model of the landscape and depict fitness peaks and valleys. Clusters in this depiction may represent local fitness peaks.

Another clear difference between Wingz and Excel was Wingz' powerful graphing system, once regarded as the most powerful available in any spreadsheet. Wingz' graphing system allowed the resulting graphs to be placed directly in the spreadsheets. At the time Excel offered an anemic variety of 2D graphs, and they could only be displayed in a separate view. Additionally Wingz made it easy to make the graphs and modify them, allowing you to see your changes in real-time directly in the spreadsheet where the changes were being made.

One of the common unifying forces that has united the community over the years has been the rather contentious relationship with TI regarding control over its graphing calculators. TI graphing calculators generally fall into two distinct groups—those powered by the Zilog Z80 and those running on the Motorola 68000 series.

Tools which allow for programming the calculators in C/C++ and possibly Fortran and assembly language are used on the computer side, such as HPGCC, TIGCC and others. Flash memory is another means of conveyance of information to and from the calculator. The on-board BASIC variants in TI graphing calculators and the languages available on HP-48 type calculators can be used for rapid prototyping by developers, professors, and students, often when a computer is not close at hand. Most graphing calculators have on-board spreadsheets which usually integrate with Microsoft Excel on the computer side.

In this variation the X-intercept gives the critical surface tension of the liquid needed to effectively wet the solid surface. There are two steps when graphing the data which are to neglect all the points around zero on the y-axis to initially plot the line of best fit to find γc ; however, when graphing the line initially if a point near 0 lands to the right of the intersection redo the regression including that point to make the measurement of the critical surface tension, γc, more accurate. A table of variables and an example can be seen below.

Most graphing calculators, as well as some non-graphing scientific calculators and programmer's calculators can be programmed to automate complex and frequently used series of calculations and those inaccessible from the keyboard. The actual programming can often be done on a computer then later uploaded to the calculators. The most common tools for this include the PC link cable and software for the given calculator, configurable text editors or hex editors, and specialized programming tools such as the below-mentioned implementation of various languages on the computer side. Earlier calculators stored programs on magnetic cards and the like; increased memory capacity has made storage on the calculator the most common implementation.

The TI-80 is a graphing calculator made by Texas Instruments. It was originally designed in 1995 to be used at a middle school level (grades 6-8). The TI-80 featured a 48 x 64 dot-matrix display with a 5 x 3 pixel font, which is the smallest screen of any TI graphing calculator. It also featured the slowest processor (980 kHz proprietary) of any TI graphing calculator. The first revision of the TI-80 'A' contained a proprietary Toshiba T6M53 ASIC while subsequent revisions contained a Toshiba T6M53A. Additionally, the TI-80 had the processor on board the ASIC, unlike later calculators like the TI-83, TI-83 Plus, and TI-84 Plus which had separate ASIC and processor chips in certain models. In comparison, the TI-81, released in 1990, featured a 2 MHz Zilog Z80 processor. However, the TI-80 did feature 7 KB of RAM (compared with the TI-81's 2.4 KB). The TI-80 also had more built-in functions than the TI-81 (such as list and table functions, as well as fraction and decimal conversions).

However, limited program address space and lack of easy program storage made calculator gaming a rarity even as programmables became cheap and relatively easy to obtain. It was not until the early 1990s when graphing calculators became more powerful and cheap enough to be common among high school students for use in mathematics. The new graphing calculators, with their ability to transfer files to one another and from a computer for backup, could double as game consoles. Calculators such as HP-48 and TI-82 could be programmed in proprietary programming languages such as RPL programming language or TI-BASIC directly on the calculator; programs could also be written in assembly language or (less often) C on a desktop computer and transferred to the calculator.

Dendrogram of multiple clusters One powerful tool for interpreting and graphing linkage data sets is called Hierarchical Clustering. Clustering organizes things into groups based on similarity. In the case of linkage, similarity equates to physical proximity on a chromosome. Hierarchical clustering is a bottom-up approach to cluster analysis, in which the two closest data points are grouped together and are treated as a single data point for later clustering.

These general conventions greatly simplified the menu structure of all the programs. Object integration was designed into the system from the start. For example, a chart object created in the graphing module could be inserted into any type of document. This type of ability eventually became available as part of the operating system on the Apple Lisa and was featured in Mac OS System 7 as Publish and Subscribe.

Skinner's student Ogden Lindsley is credited with forming a movement called precision teaching, which developed a particular type of graphing program called the standard celeration chart to monitor the progress of clients. Skinner became interested in the individualising of programs for improved learning in those with or without disabilities and worked with Fred S. Keller to develop programmed instruction. Programmed instruction had some clinical success in aphasia rehabilitation.Goldfarb, R. (2006).

Roughly fifteen years after CHIP-8 was introduced, derived interpreters appeared for some models of graphing calculators (from the late 1980s onward, these handheld devices in many ways have more computing power than most mid-1970s microcomputers for hobbyists). An active community of users and developers existed in the late 1970s, beginning with ARESCO's "VIPer" newsletter whose first three issues revealed the machine code behind the CHIP-8 interpreter.

INPhO consists of, usually, about 6 subjective problems, which the students must solve in 3 hours. Use of a non-programmable scientific calculator is usually allowed, as long as it has less than 4 lines in its display, no graphing feature and no CAS-like functionality. The total marks vary each year. Earlier, the syllabus matched that of IPhO, but now, it is broadly equivalent to the syllabus of NSEP.

The upper grades begin studying business math, pre-algebra, and algebra, including graphing equations. Science is introduced in the lower grades through observation and experience with nature, as well as gardening and cooking. Science continues in the middle grades with zoology, botany, and astronomy, and in the upper grades with physics, chemistry, anatomy, mechanics, and meteorology. Social Studies begins in the earlier grades with legends, myths, and folklore.

Of historical interest is the cumulative recorder, an instrument used to record the responses of subjects graphically. Traditionally, its graphing mechanism has consisted of a rotating drum of paper equipped with a marking needle. The needle would start at the bottom of the page and the drum would turn the roll of paper horizontally. Each subject response would result in the marking needle moving vertically along the paper one tick.

The G & M code positions are all based on a three dimensional Cartesian coordinate system. This system is a typical plane often seen in mathematics when graphing. This system is required to map out the machine tool paths and any other kind of actions that need to happen in a specific coordinate. Absolute coordinates are what is generally used more commonly for machines and represent the (0,0,0) point on the plane.

This means that while large mussels have a higher energy content (E), they also have a longer handling time (h). The profitability of any mussel is calculated as E/h. The oystercatchers must decide which mussel size will provide enough nutrition to outweigh the cost and energy required to open it. In their study, Meire and Ervynck tried to model this decision by graphing the relative profitabilities of different sized mussels.

Graphing implied volatilities against strike prices for a given expiry yields a skewed "smile" instead of the expected flat surface. The pattern differs across various markets. Equity options traded in American markets did not show a volatility smile before the Crash of 1987 but began showing one afterwards. It is believed that investor reassessments of the probabilities of fat-tail have led to higher prices for out-of-the-money options.

Advantages of Parflange F37 compared to welded flange connections are mainly in savings on time and costs. No costly inspection of welds (f.e. by x-ray graphing) and post-weld acid cleaning is needed, making the connection also more environment-friendly and safer then welding. Compared to welding, no welding stress corrosion is possible, resulting in maximum service time of the pipe connection and a reduction of service costs.

The numbers are binned based on the first significant digit, and within each stack binned again based on the second significant digit. On the other hand, Q-Q plots compare two probability distributions by graphing quantiles against each other. This allows the viewer to see if the plot values are similar and if the two are linearly related. SPLOM is a technique that represents the relationships among multiple variables.
|
|
It uses multiple scatter plots to represent a pairwise relation among variables. Another statistical distribution approach to visualize multivariate data is parallel coordinates. Rather than graphing every pair of variables in two dimensions, the data is repeatedly plotted on a parallel axis and corresponding points are then connected with a line. The advantage of parallel coordinates is that they are relatively compact, allowing many variables to be shown simultaneously.

If f is an irreducible polynomial of prime degree p with rational coefficients and exactly two non-real roots, then the Galois group of f is the full symmetric group S_p. For example, f(x)=x^5-4x+2 \in \Q[x] is irreducible from Eisenstein's criterion. Plotting the graph of f with graphing software or paper shows it has three real roots, hence two complex roots, showing its Galois group is S_5.

Like many Casio calculators, the FX-7000G includes a programming mode, in addition to its display and graphing mode. It holds 422 bytes of programming memory, less than half a kilobyte. However the calculator does allow for expanded/additional memory by a method of reducing the number of steps within a program. This is done by optimizing the number of steps a program has to fill a single unit of memory, instead of several.

Casio issued an SDK which amongst other things produced a programmable interpreter/compiler called OWBasic put together by Wolfgang Ortmann. OWBasic was an implementation of the BASIC programming language. OWbasic has most of the BASIC commands such as proc, gosub, conditional if/then statements and some others for graphing. OWBasic also allows a user to develop applications for string text, taking the CasioPV beyond the normal limits imposed by a standard programmable calculator.

This can be illustrated by graphing the short run total cost curve and the short-run variable cost curve. The shapes of the curves are identical. Each curve initially increases at a decreasing rate, reaches an inflection point, then increases at an increasing rate. The only difference between the curves is that the SRVC curve begins from the origin while the SRTC curve originates on the positive part of the vertical axis.

AlphaSmart uses the DragonBall family in later versions of its portable word processors. Texas Instruments uses the 68000 in its high-end graphing calculators, the TI-89 and TI-92 series and Voyage 200. Early versions of these used a specialized microcontroller with a static 68EC000 core; later versions use a standard MC68SEC000 processor. A modified version of the 68000 formed the basis of the IBM XT/370 hardware emulator of the System 370 processor.

An M-y diagram is a plot of the depth of flow (y) versus momentum (M). In this case M does not refer to momentum (M/Lt2), but to the momentum function (L3 or L2). This produces a specific momentum curve that is generated by calculating momentum for a range of depth values and graphing the results. Each M-y curve is unique for a specific flowrate, Q, or unit discharge, q.

Fancy Pants Man (left) fights against Newgrounds mascot Pico (middle) and Alien Hominid in Newgrounds Rumble. The Fancy Pants Adventures series was created by Brad Borne, who had previously created games with the help of Mark Fleig Jr. Fleig provided all of the computer graphics on their collaborations. The previous games provided experience and allowed for more complex designs. Before using Macromedia Flash Borne had experimented with the TI-BASIC programming language on a TI-86 graphing calculator.

To visualize the motivation behind rejection sampling, imagine graphing the density function of a random variable onto a large rectangular board and throwing darts at it. Assume that the darts are uniformly distributed around the board. Now remove all of the darts that are outside the area under the curve. The remaining darts will be distributed uniformly within the area under the curve, and the x-positions of these darts will be distributed according to the random variable's density.

The explanation was that the update added asymptote checking in graphing. In January 2006, Texas Instruments released v2.40 of the operating system for the TI-84 Plus series. The most noticeable addition to the new OS was the "Press- To-Test" feature that allowed a teacher to disable any programs installed on the calculator, so they cannot be used on tests, etc. As of OS version 2.53MP which was released in February 2010, support was added for prettyprinted expressions.

Throughout the 1980s, Texas Instruments worked closely with National Council of Teachers of Mathematics (NCTM) to develop a calculator to become the educational standard. In 1986, Connecticut School Board became the first to require a graphing calculator on state-mandated exams. Chicago Public Schools gave a free calculator to every student, beginning in the fourth grade, in 1988. New York required the calculator in 1992 for its Regents exams after first allowing it the previous year.

HubNet is a technology that uses NetLogo to run participatory simulations in the classroom. In a participatory simulation, a whole group of users takes part in enacting the behavior of a system. Using an individual device, such as a networked computer or Texas Instruments graphing calculator, each user acts as a separate, independent agent. One example of a HubNet activity is Tragedy of the Commons, which models the economic problem called the tragedy of the commons.

David Shuman; Indent Grapher (Dureza) Software Spreadsheet programs such as MS-Excel or OpenOffice Calculate do not have the ability to fit to the non-linear power law equation from indentation data. A linear fit can be done by offset (-h(P_0)) displacement so that the data passes through the origin. Then select the power law equation from the graphing XY options. The Martens hardness, HM, is a simple software for any programmer having minimal background to develop.

Like the TI-81, the TI-80 did not feature a link port on the base model, however, unlike the TI-81, the ViewScreen variant (meant for use with TI's overhead projection units) did. The TI-80 was also the only graphing calculator to use 2 CR2032 lithium batteries (instead of the standard 4 AAA batteries with a lithium backup battery). Since its release, it has been superseded by the superior TI-73 and TI-73 Explorer.

It was created partially in response to the fact that while calculators are allowed on many standardized tests, the TI-92 was considered a computer due to the QWERTY layout of its keyboard. Additionally, some people found the TI-92 unwieldy and overly large. The TI-89 is significantly smaller—about the same size as most other graphing calculators. It has a flash ROM, a feature present on the TI-92 Plus but not on the original TI-92.

The results of these tests are plotted using a graphing technique known as a shmoo plot that indicates clearly the boundary limit beyond which a device begins to fail for a given combination of these environmental conditions. Corner-lot analysis is most effective in digital electronics because of the direct effect of process variations on the speed of transistor switching during transitions from one logic state to another, which is not relevant for analog circuits, such as amplifiers.

The Calculator-Based Laboratory (CBL) is a mobile data collection device manufactured by Texas Instruments in collaboration with Vernier Software & Technology and introduced in 1994. The CBL can be used to collect data either in conjunction with a TI graphing calculator, or on its own. Different from programming languages, it consists of a set of commands starting with a colon (:) which are to be executed in existing applications such as the default calculator and the graphical calculation program.

52 Misleading graphs may be created intentionally to hinder the proper interpretation of data or accidentally due to unfamiliarity with graphing software, misinterpretation of data, or because data cannot be accurately conveyed. Misleading graphs are often used in false advertising. One of the first authors to write about misleading graphs was Darrell Huff, publisher of the 1954 book How to Lie with Statistics. The field of data visualization describes ways to present information that avoids creating misleading graphs.

On remote control devices, the buttons on the d-pad function in the same manner as other buttons, and are generally used to navigate on-screen menus. Though initially not common, the quick success of the DVD format led to wide availability of remote designs with D-pads circa 2000, and most current menu-driven consumer electronics devices include some sort of d-pad on the remote (and, occasionally, on the unit itself). In addition, many small computing and communications devices, particularly PDAs, mobile phones, and GPS receivers, include d-pads not only for menu navigation but as general input devices similar to a joystick or mouse. Less-sophisticated designs similar to those on remote controls appear on some calculators, particularly scientific and graphing calculators, which use the d-pad for cursor control on multi-line screens, as well as input/output recall, menu navigation, and occasionally direct screen access (graphing calculators in particular allow the use of the d-pad to determine values at specific points on a displayed graph).

TI-BASIC is the built in language for TI-83 series calculators, as well as many other TI graphing calculators. TI-BASIC is a non-structured programming language, meaning it is arranged sequentially, without the use of methods or organized blocks of code. Due to its simplicity and the ubiquity of TI calculators in school curricula, for many students it is their first experience with programming. Below is an example of a hello world program equivalent to the assembly language example.

The output of the colorimeter is then fed back to the computer for processing. The output consists of a printout to the teletype and a graph drawn by a pen and ink recorder. Once the process is complete, the computer determines the time and the percentage of each amino acid present as they exited the separation tube. Since different molecules pass through the resin tube at various speeds, graphing the output of the colorimeter against time indicates which amino acid is present.

In 1990, a CHIP-8 interpreter called CHIP-48 was made for HP-48 graphing calculators so games could be programmed more easily. Erik Bryntse later created another interpreter based on CHIP-48, called SCHIP, S-CHIP or Super-Chip. SCHIP extended the CHIP-8 language with a larger resolution and several additional opcodes meant to make programming easier. If it were not for the development of the CHIP-48 interpreter, CHIP-8 would not be as well known today.

The different games a player encounters when trying to get the Zoombinis from Zoombini Isle to Zoombiniville represent many mathematical characteristics. "Pizza Pass", "Allergic Cliffs", and "Stone Cold Caves" exercise the sorting, grouping, and comparing of information. "Captain Cajun's Ferryboat", "Stone Rise", and "Titanic Tattooed Toads" reinforce ordering, linking information, and problem solving. "Fleens!", "Mudball Wall", and "Hotel Dimensia" emphasize graphing and mapping, while "Lions' Lair", "Mirror Machine", and "Bubblewonder Abyss" train the player in sorting, organizing, and algebraic thinking.

Support for both assertions rests upon interpreting the patterns produced from graphing the paired measures, The most common graphical convention is the Kruger–Dunning type graph used in the seminal paper. That paper depicted college students' accuracy in self-assessing their competencies in humor, logical reasoning, and grammar. Researchers adopted that convention in subsequent papers on the effect. Additional graphs used by other researchers who argued for the legitimacy of the effect include (y-x) versus (x) cross plots and bar charts.

The TI-92 series of graphing calculators are a line of calculators produced by Texas Instruments. They include: the TI-92 (1995), the TI-92 Plus (1998, 1999), and the Voyage 200 (2002). The design of these relatively large calculators includes a QWERTY keyboard. Because of this keyboard, it was given the status of a "computer" rather than "calculator" by American testing facilities and cannot be used on tests such as the SAT or AP Exams while the similar TI-89 can be.

Programmable calculators are calculators that can automatically carry out a sequence of operations under control of a stored program, much like a computer. The first programmable calculators such as the IBM CPC used punched cards or other media for program storage. Hand-held electronic calculators store programs on magnetic strips, removable read-only memory cartridges, flash memory, or in battery-backed read/write memory. Since the early 1990s, most of these flexible handheld units belong to the class of graphing calculators.

Although this rendered the traditional assembly shell unnecessary on the TI-83 hardware, calculator programmers continued to develop shells to supplement or replace the standard operating system. Since the TI-83, TI has supported assembly-level programming on all subsequent graphing calculators, though similar shell hacks needed to be created for older hardware, such as the TI-82 and the TI-92. Hewlett-Packard also supports assembly language programming, though onboard programming tools mean that a separate shell is not needed.

Charting on Lotus 1-2-3 Release 2.2 for DOS Examples of Lotus 1-2-3 macros The name "1-2-3" stemmed from the product's integration of three main capabilities. Along with being a spreadsheet, it also offered integral charting/graphing and rudimentary database operations. Data features included sorting data in any defined rectangle, by order of information in one or two columns in the rectangular area. Justifying text in a range into paragraphs allowed it to be used as a primitive word processor.

As evident by the equation, initial Pb isotope ratios, as well as the age of the system are the two factors which determine the present day Pb isotope compositions. If the sample behaved as a closed system then graphing the difference between the present and initial ratios of 207Pb/204Pb versus 206Pb/204Pb should produce a straight line. The distance the point moves along this line is dependent on the U/Pb ratio, whereas the slope of the line depends on the time since Earth's formation.

The calculator requirements are stricter than the SAT's in that computer algebra systems (such as the TI-89) are not allowed; however, the ACT permits calculators with paper tapes, that make noise (but must be disabled), or that have power cords with certain "modifications" (i.e., disabling the mentioned features), which the SAT does not allow. Standard graphing calculators, such as the TI-83 and TI-84, are allowed. Within the TI-Nspire family, the standard and CX versions are allowed while the CX CAS is not.

In 1961, the remnants of van 218 Z (ex 241 D) were modified such that it could be used to test clearances for special loads going to Gippsland, for the Hazelwood Power Station project. A pantograph was fitted with a graphing device which recorded the height of the overhead contact wire. The vehicle was stored at Newport Workshops when not in use. It is thought that the vehicle was not used beyond 1974; it was later sold to Simsmetal and scrapped on 22 December 1979.

Computer Games Museum in Berlin Video games require a platform, a specific combination of electronic components or computer hardware and associated software, to operate. The term system is also commonly used. Games are typically designed to be played on one or a limited number of platforms, and exclusivity to a platform is used as a competitive edge in the video game market. The list below is not exhaustive and excludes other electronic devices capable of playing video games such as PDAs and graphing calculators.

One example of the appliance in use would be a healthcare organization that hopes to find, among its 13 million patient records, information that doctors could use to develop treatment plans. Graphing the records of existing patients by categories such as illness, age, treatment and outcome may provide guidance on treating another patient. Big data is also being tapped in professional sports. In 2014, Cray revealed that a Major League Baseball team was using a Urika-GD appliance to graph and analyze its own performance statistics.

Graphics Layout Engine (GLE) is a graphics scripting language designed for creating publication quality graphs, plots, diagrams, figures and slides. GLE supports various graph types such as function plots, histograms, bar graphs, scatter plots, contour lines, color maps and surface plots through a simple but flexible set of graphing commands. More complex output can be created by relying on GLE's scripting language, which is full featured with subroutines, variables, and logic control. GLE relies on LaTeX for text output and supports mathematical formula in graphs and figures.

Enthusiasts analyzed memory backups and discovered that entries in the calculator's CUSTOM menu pointed at specific memory locations. With this knowledge, a hack was devised where a special string could be inserted into the backup at the proper location to allow the calculator to execute assembly language programs. These programs could run much faster than their BASIC counterparts and be much more efficient in terms of memory usage. This development made the TI-85 the first TI graphing calculator that could execute assembly programs.

Usb8x is a flash application for the TI-84+ and TI-84+SE graphing calculators. It is a driver that interfaces with the calculator's built in USB On-The-Go port, allowing developers to easily create their own USB device drivers for use on the calculators. This allows the newfound use of USB peripherals such as a USB mouse, USB keyboard, or a USB flash drive. The programming is currently in alpha/beta testing for both TI-BASIC and flash application storage and management.

Along the trailing vertical (y axis) rail slides a smaller carriage holding a tracing point. Along the leading vertical rail slides a second smaller carriage to which is affixed a small, sharp disc, which rests and rolls (but does not slide) on the graphing paper. The trailing carriage is connected both with a point in the center of the carriage and the disc on the leading rail by a system of sliding crossheads and wires, such that the tracing point must follow the disc's tangential path.

Cabri Geometry is a commercial interactive geometry software produced by the French company Cabrilog for teaching and learning geometry and trigonometry... It was designed with ease-of-use in mind. The program allows the user to animate geometric figures, proving a significant advantage over those drawn on a blackboard. Relationships between points on a geometric object may easily be demonstrated, which can be useful in the learning process. There are also graphing and display functions which allow exploration of the connections between geometry and algebra.

He later became interested in statistical computing, and stressed that "a computer should make both calculations and graphs", and illustrated the importance of graphing data with four data sets now known as Anscombe's quartet. He later published a textbook on statistical computing in APL. In economics and decision theory he is best known for a 1963 paper with Robert Aumann which provides the standard basis for the theory of subjective probability. He was brother-in-law to another well-known statistician, John Tukey of Princeton University; their wives were sisters.

The Z80 was a common choice for creators of video games during the Golden age of arcade video games, with a Z80 powering Pac-Man, dual Z80s in Scramble, and three in each Galaga machine. It was the central processor for the ColecoVision game console (1982), Sega's Master System (1986) and Game Gear (1990), and the over 100 million unit selling Nintendo Game Boy (1989). In the 1990s, the Z80 was the CPU of the Texas Instruments graphing calculator series, as well as being used as the sound CPU in the Sega Genesis.

Scientific mode supports exponents and trigonometric functions, and programmer mode gives the user access to more options related to computer programming. The Calculator program has a long associated history with the beginning of the Macintosh platform, where a simple four-function calculator program was a standard desk accessory from the earliest system versions. Though no higher math capability was included, third-party developers provided upgrades, and Apple released the Graphing Calculator application with the first PowerPC release (7.1.2) of the Mac OS, and it was a standard component through Mac OS 9.

The TI-Nspire series I/O has a connector for the TI-Nspire Lab Cradle, another that serves as a connector for TI's wireless network adapter, and a Mini-USB connector for transferring data. The TI-Nspire series is available with and without a computer algebra system. In 2011, Texas Instruments released the CX line of their TI-Nspire calculators which effectively replaced the previous generation. The updates included improvements to the original's keyboard layout, an addition of a rechargeable lithium-ion battery, 3D graphing capabilities and reduced form factor.

There was also a "Geography Quiz" and several other games and quizzes, some quizzes also in Encarta Kids. For years, Encarta came in three primary software editions: Standard, Premium, and Reference Library (price and features in that order). Beginning with Encarta 2006, however, when Websters Multimedia took over its maintenance, Encarta became a feature of Microsoft Student. Although it was possible to purchase only the Encarta encyclopedia separately, Microsoft Student bundles together Encarta Premium with Microsoft Math (a graphing-calculator program) and Learning Essentials, which provides templates for Microsoft Office.

The TI-84 Plus is a graphing calculator made by Texas Instruments which was released in early 2004. There is no original TI-84, only the TI-84 Plus, the TI-84 Plus Silver Edition models, and the TI-84 Plus CE. The TI-84 Plus is an enhanced version of the TI-83 Plus. The key-by-key correspondence is relatively the same, but the 84 features some improved hardware. The archive (ROM) is about 3 times as large, and CPU about 2.5 times as fast (over the TI-83 and TI-83 Plus).

Another popular version is Drug Wars - Underworld; a fantasy-themed version called Dragon TraderDragon Trader also exists. In 1998, Michael Swain released a modified port of the original TI-82 Drug Wars, for the TI-83 and TI-83+ graphing calculators. In 1999, Jason Roberts released a version for the TI-83 called DrugWars 2: International that added RPG elements which included fights with cops. In 1995, a TI-Basic game titled pimpwars was released for the TI-82 that included new features such as sex trade, drug addiction management, and a simple driving simulation.

In 1987, TI invented the digital light processing device (also known as the DLP chip), which serves as the foundation for the company's award-winning DLP technology and DLP Cinema. TI released the popular TI-81 calculator in 1990, which made it a leader in the graphing calculator industry. Its defense business was sold to Raytheon in 1997; this allowed TI to strengthen its focus on digital solutions. After the acquisition of National Semiconductor in 2011, the company had a combined portfolio of 45,000 analog products and customer design tools.

Black-box testing involves testing interfaces and the integration of the database, which includes: # Mapping of data (including metadata) # Verifying incoming data # Verifying outgoing data from query functions # Various techniques such as Cause effect graphing technique, equivalence partitioning and boundary-value analysis. With the help of these techniques, the functionality of the database can be tested thoroughly. Pros and Cons of black box testing include: Test case generation in black box testing is fairly simple. Their generation is completely independent of software development and can be done in an early stage of development.

In RPN mode, it uses a four-level stack, as have all HP's non-graphing RPN calculators since the earliest days. In contrast to the usual computer-science terminology, RPN calculators such as this refer to the operational end of the stack as the bottom and the far end as the top. The stack levels are named X (the bottom), Y, Z, and T (the top); they have no connection with the variables of the same names. Level X appears on the lower line of the display and level Y on the upper line.

The Commodore Plus/4 is a home computer released by Commodore International in 1984. The "Plus/4" name refers to the four-application ROM resident office suite (word processor, spreadsheet, database, and graphing); it was billed as "the productivity computer with software built-in." Internally, the Plus/4 shared the same basic architecture as the lower-end Commodore 16 and 116 models, and was able to use software and peripherals designed for them. The Plus/4 was incompatible with the Commodore 64's software and some of its hardware.

The TI-82 was redesigned twice, first in 1999 and again in 2001. The 1999 redesign introduced a design very similar to the TI-73, TI-83 Plus, and the TI-89. It introduced a more contoured body and eliminated the sloped screen that has been common on TI graphing calculators since the TI-81. The 2001 redesign (nicknamed the TI-82 "Parcus")TI-82 Parcus – DATAMATH introduced a slightly different shape to the calculator, eliminated the glossy screen border, and reduced cost by streamlining the printed circuit board to four units.

The TI-81 is an early graphing calculator made by Texas Instruments. It was designed in 1990 for use in algebra and precalculus courses. Since its original release, it has been superseded several times by newer calculators: the TI-85, TI-82, TI-83, TI-86, TI-83 Plus, TI-83 Plus Silver Edition, TI-84 Plus, TI-84 Plus Silver Edition, and most recently the TI-Nspire and TI-Nspire CAS. Most of these share the original feature set and 96×64-pixel display that began with this calculator.

At the turn of the millennium, the line between a graphing calculator and a handheld computer was not always clear, as some very advanced calculators such as the TI-89, the Voyage 200 and HP-49G could differentiate and integrate functions, solve differential equations, run word processing and PIM software, and connect by wire or IR to other calculators/computers. The HP 12c financial calculator is still produced. It was introduced in 1981 and is still being made with few changes. The HP 12c featured the reverse Polish notation mode of data entry.

On graphing calculators, an assembly shell is a program that is used to run other programs written in the calculator's native machine code rather than the calculator's standard high-level programming language. While all assembly shells can run assembly programs, some can also run high-level programs. For example, MirageOS and DoorsCS, two popular TI-83+ assembly shells, can run TI- BASIC programs by placing a colon as the first bit of code on the first line in the program. Assembly shells were created when calculator manufacturers did not support native-code programming.

Mariners have long known that these measures do not completely cancel deviation; hence, they performed an additional step by measuring the compass bearing of a landmark with a known magnetic bearing. They then pointed their ship to the next compass point and measured again, graphing their results. In this way, correction tables could be created, which would be consulted when compasses were used when traveling in those locations. Mariners are concerned about very accurate measurements; however, casual users need not be concerned with differences between magnetic and true North.

The rotation of Jupiter's polar atmosphere is about 5 minutes longer than that of the equatorial atmosphere; three systems are used as frames of reference, particularly when graphing the motion of atmospheric features. System I applies from the latitudes 10° N to 10° S; its period is the planet's shortest, at 9h 50m 30.0s. System II applies at all latitudes north and south of these; its period is 9h 55m 40.6s. System III was first defined by radio astronomers, and corresponds to the rotation of the planet's magnetosphere; its period is Jupiter's official rotation.

Designed for use by high school and college students, though now used by middle school students in some public school systems, it contains all the features of a scientific calculator as well as function, parametric, polar, and sequential graphing capabilities; an environment for financial calculations; matrix operations; on-calculator programming; and more. Symbolic manipulation (differentiation, algebra) is not built into the TI-83 Plus. It can be programmed using a language called TI-BASIC, which is similar to the BASIC computer language. Programming may also be done in TI Assembly, made up of Z80 assembly and a collection of TI provided system calls.

In function graphing, a horizontal translation is a transformation which results in a graph that is equivalent to shifting the base graph left or right in the direction of the x-axis. A graph is translated k units horizontally by moving each point on the graph k units horizontally. For the base function f(x) and a constant k, the function given by g(x) = f(x − k), can be sketched f(x) shifted k units horizontally. If function transformation was talked about in terms of geometric transformations it may be clearer why functions translate horizontally the way they do.

TilEm is an emulator that simulates certain Texas Instruments calculators on a generic computer. It is similar to TiEmu, uses GTK+, and works on many different operating systems like Linux/Unix, FreeBSD, 32-bit Microsoft Windows and so on. If you have a copy of the information in the ROM from one of the ZiLOG Z80 series Texas Instruments Graphing Calculators (TI-82, TI-83 series, TI-84 Plus series, TI-85, TI-86, and TI-81), TilEm will emulate the behavior of the calculator without requiring the actual calculator hardware. TilEm is licensed under the GPL License.

An apple in pixel art Pixel art is a form of digital art, created through the use of software, where images are edited on the pixel level. The aesthetic for this kind of graphics comes from 8-bit and 16-bit computers and video game consoles, in addition to other limited systems such as graphing calculators. In most pixel art, the color palette used is extremely limited in size, with some pixel art using only two colors. Creating or modifying pixel art characters or objects for video games is sometimes called spriting, a term that arose from the hobbyist community.

The TI-Nspire is a graphing calculator made by Texas Instruments which was released in July 2007. The original TI-Nspire was developed out of the TI PLT SHH1 prototype calculator (which itself was derived from the Casio ClassPad 300), the TI-92 series of calculators released in 1995, and the TI-89 series of calculators released in 1998. The TI-Nspire features a non-QWERTY keyboard and a different key-by-key layout compared to its predecessors. The TI-Nspire allows users to swap out the existing removable keypad with a functional copy of the TI-84 Plus series keypad.

There are a wide range of applications that this produces, from science classes, to games, to calculus to note taking (when put together with a separately sold keyboard). The TI-84 Plus Series is exactly like its predecessor in that it can be used on the SAT and ACT examinations as well as International Baccalaureate examinations. However, in some cases those administering the exam may reset the calculator's memory beforehand to prevent cheating through the use of built in programs or other data. When OS 2.30 was initially released, users noticed the speed of graphing was greatly reduced.

Even though handheld gaming devices fall in a similar price range, graphing calculators offer superior math programming capability for math based games. However, for developers and advanced users like researchers, analysts and gamers, third party software development involving firmware modifications, whether for powerful gaming or exploiting capabilities beyond the published data sheet and programming language, is a contentious issue with manufacturers and education authorities as it might incite unfair calculator use during standardized high school and college tests where these devices are targeted. Nowadays graduate (Masters) students and researchers have turned to advanced Computer Aided Math software for learning as well as experimenting.

Laws began using similar devices in her teaching lab, and as Laws's son owned an Atari 8-bit computer, began development of a recording and graphing system on that platform. The Atari was ideal for the task for two reasons. One was because it had a high-resolution graphics mode that was, at the time of introduction, one of the best displays available and easily accessed through Atari BASIC. Another was that the engineers had equipped it with joystick ports of unusual flexibility, which allowed them to be used as a general purpose voltage sampling input.

Most American upper-level middle school algebra courses generally tend to use the TI-83 or TI-84 families instead of the TI-73 or TI-73 Explorer, while most basic middle school math courses generally do not use graphing calculators, instead opting for scientific calculators such as the TI-30 or TI-34 families. Originally the TI-73 could only run programs written in TI-BASIC, although that has changed in recent years. In 2005 an assembly shell called Mallard was released for the TI-73. Mallard allows the user to run programs written in assembly language.

Patrick Madison, a CSM computer science instructor, and Dan Smith, a graduate student, began a partnership in 1983 with the development of a printer interface language that took advantage of the full resolution available to dot-matrix printers. Their first commercial program, PlotCall, transformed plotter instructions into dot-matrix instructions compatible with over 20 commercial printers. This opened the computer graphing and mapping market to the wider arena of users with inexpensive commercial printers. Between 1985 and 1986 the company released two DOS applications: Surfer, a surface and contour mapping program, and Grapher, a spreadsheet-plotting application.

In math, students may learn about addition and subtraction of natural numbers, usually with only one digit, and about measurement. Basic geometry and graphing may be introduced. Clock and calendar time as well as money may also be in the curriculum. In language, first graders are taught the fundamentals of literacy, including reading sentences, writing very simple statements and mastery of the alphabet, building on what the students have learned in kindergarten or other forms of pre-school (although because first grade is the first compulsory level of education in many U.S. states, the level of literacy in incoming students can vary widely).

These approximations are only valid near, but not at, the end point, and so the method differs from end point estimations by way of first- and second-derivative plots, which require data at the end point. Gran plots were originally devised for graphical determinations in pre-computer times, wherein an x-y plot on paper would be manually extrapolated to estimate the x-intercept. The graphing and visual estimation of the end point have been replaced by more accurate least-squares analyses since the advent of modern computers and enabling software packages, especially spreadsheet programs with built-in least-squares functionality.

On Thursday afternoons, the children were required to spend two hours tallying up their daily statistics to determine their status in accordance with the concept of Scientology ethics. Depending on the outcome of the graphing, the children would have to take particular steps to improve or maintain their statistics. If the trend was down, potentially negative consequences would follow, such as having privileges revoked or being given only rice and beans to eat. The children were also given weekly E-meter checks to determine whether they were concealing secrets or transgressions, and had to write weekly reports to their parents.

Excel became the first spreadsheet to allow the user to define the appearance of spreadsheets (fonts, character attributes, and cell appearance). It also introduced intelligent cell re-computation, where only cells dependent on the cell being modified are updated (previous spreadsheet programs recomputed everything all the time or waited for a specific user command). Excel introduced auto-fill, the ability to drag and expand the selection box to automatically copy a cell or row contents to adjacent cells or rows, adjusting the copies intelligently by automatically incrementing cell references or contents. Excel also introduced extensive graphing capabilities.

Edge gameplay mocked up on a Sony Ericsson W880i mobile phone A mobile game is a game played on a mobile phone (feature phone or smartphone), tablet, smartwatch, PDA, portable media player or graphing calculator. The earliest known game on a mobile phone was a Tetris variant on the Hagenuk MT-2000 device from 1994. In 1997, Nokia launched the very successful Snake. Snake (and its variants), that was preinstalled in most mobile devices manufactured by Nokia, has since become one of the most played games and is found on more than 350 million devices worldwide.

Clone of Tetris being played on a TI-83 Plus Portal Calculator gaming is a form of gaming in which games are played on programmable calculators, especially graphing calculators. An early example is the type-in program Darth Vader's Force Battle for the TI-59, published in BYTE in October 1980. The magazine also published a version of Hunt the Wumpus for the HP-41C. Few other games exist for the earliest of programmable calculators (including the Hewlett-Packard 9100A, one of the first scientific calculators), such as the long-popular Lunar Lander game often used as an early programming exercise.

The TI-89 is a graphing calculator developed by Texas Instruments in 1998. The unit features a 160×100 pixel resolution LCD screen and a large amount of flash memory, and includes TI's Advanced Mathematics Software. The TI-89 is one of the highest model lines in TI's calculator products, along with the TI-Nspire. In the summer of 2004, the standard TI-89 was replaced by the TI-89 Titanium. The TI-89 runs on a 32-bit microprocessor, the Motorola 68000, which nominally runs at 10, 12 MHz, depending on the calculator's hardware version.

Interactive Visual Analysis (IVA) is a set of techniques for combining the computational power of computers with the perceptive and cognitive capabilities of humans, in order to extract knowledge from large and complex datasets. The techniques rely heavily on user interaction and the human visual system, and exist in the intersection between visual analytics and big data. It is a branch of data visualization. IVA is a suitable technique for analyzing high-dimensional data that has a large number of data points, where simple graphing and non-interactive techniques give an insufficient understanding of the information.

Scott started programming at the age of 12, by writing games for her TI-89 graphing calculator and sharing them with friends in middle school. She learned the Java and C++ programming languages and the MIPS architecture at Amherst College, but taught herself the skills she used for writing her own applications in Python, Objective C, and iOS. She says that though she enjoyed programming in college, she went into acting and modeling professionally because she never saw herself spending her life around other computer programmers; after graduating, most of her programming was done alone. By 2017, she considered herself primarily a programmer.

Any American high school student (or middle school, though the competition may be too challenging for all but the brightest of these) may compete in a team of up to five people. Students are not required to be students of the same school, or even residents of the same state. Because of the decentralized nature of the competition, an advisor such as a teacher of a guardian is required for each team to monitor the team and vouch for compliance with the competition's rules. No computer or calculator programs or applications are allowed on the iTest, though graphing calculator use is allowed.

Webster West created StatCrunch in 1997. Over the next 19 years Webster West,Webster West "The Impact Of Technology On The Teaching Of Statistics" Consortium for the Advancement of Undergraduate Statistics Education (2012) assisted by others, added many more statistical procedures and graphing capabilities, and made user interface improvements. In 2005, Webster West received two awards for StatCrunch: the CAUSEweb Resource of the Year Award and the MERLOT Classics Award. In 2013, the StatCrunch Java code was rewritten in JavaScript in order to avoid Java browser security problems, and so that it would run on iOS and Android.

HP 39/40 series are graphing calculators from Hewlett-Packard, the successors of HP 38G. The series consists of six calculators, which all have algebraic entry modes, and can perform numeric analysis together with varying degrees of symbolic calculation. All calculators in this series are aimed at high school level students and are characterized by their ability to download (via cable or infra-red) APLETs or E-lessons. These are programs of varying complexity which are generally intended to be used in the classroom to enhance the learning of mathematics by the graphical and/or numerical exploration of concepts.

After previewing 1-2-3 on the IBM PC in 1982, BYTE called it "modestly revolutionary" for elegantly combining spreadsheet, database, and graphing functions. It praised the application's speed and ease of use, stating that with the built-in help screens and tutorial "1-2-3 is one of the few pieces of software that can literally be used by anybody. You can buy 1-2-3 and [an IBM PC] and be running the two together the same day". PC Magazine in 1983 called 1-2-3 "a powerful and impressive program ... as a spreadsheet, it's excellent", and attributed its very fast performance to being written in assembly language.

Although it does not include as many calculus functions, applications and programs can be written on the calculator or loaded from external sources. The TI-83 was redesigned twice, first in 1999 and again in 2001. TI replaced the TI-83 with the TI-83 Plus in 1999. The redesign introduced a design very similar to the TI-73 and TI-83 Plus, eliminating the sloped screen that had been common on TI graphing calculators since the TI-81, and included Flash memory, enabling the device's operating system to be updated if needed, or for large new Flash Applications to be stored, accessible through a new Apps key.

HyperCard can be extended significantly through the use of external command (XCMD) and external function (XFCN) modules. These are code libraries packaged in a resource fork that integrate into either the system generally or the HyperTalk language specifically; this is an early example of the plug-in concept. Unlike conventional plug-ins, these do not require separate installation before they are available for use; they can be included in a stack, where they are directly available to scripts in that stack. During HyperCard's peak popularity in the late 1980s, a whole ecosystem of vendors offered thousands of these externals such as HyperTalk compilers, graphing systems, database access, Internet connectivity, and animation.

Electronika MK-71 Most notable is a line of calculators, which started production in 1968. The Electronika calculators were produced in a variety of sizes and function sets, ranging from large, bulky four-function calculators to smaller models designed for use in schools operating on a special, safer 42V standard (like the MK-SCH-2). As time progressed, Electronika calculators were produced that supported more advanced calculations, with some of the most recent models even offering full programmability and functionality similar to today's American-designed graphing calculators. The Electronika brand is now used by Novosibirsk RPN programmable calculators Electronika MK-152 (:ru:Электроника МК-152) and Electronika MK-161 (:ru:Электроника МК-161).

This is obviously at odds with genetic algorithms, the quintessential evolutionary computation algorithm that selects good solutions in an attempt to make better solutions. The resulting dynamics of this simple principle is firstly a robust hill climbing search behaviour, and secondly a diversity mechanism that resembles that of multiple-restart search. Graphing holistic solution quality over time (algorithm iterations) shows periods of improvement followed by quality crashes (avalanche) very much in the manner as described by punctuated equilibrium. It is these crashes or dramatic jumps in the search space that permit the algorithm to escape local optima and differentiate this approach from other local search procedures.

AirQ+ is intended as a tool to ascertain the magnitude of the burden and impacts of air population on health in a given locality. It performs this function by featuring data analysis, graphing tools, tables and quantitative information for prominent pollutants such as particulate matter (PM), nitrogen dioxide (NO2), and tropospheric ozone (O3). AirQ+ also has the capacity to perform calculations for black carbon (BC) and provides rough estimates of impacts of household (indoor) air pollution on health. AirQ+ can be applied to long- and short-term exposure to ambient air pollution and to long-term household air pollution exposure caused by solid fuel use.

The TI-81 is powered by a Zilog Z80 microprocessor, like those used in almost every other Texas Instruments graphing calculator (except the TI-80, TI-89, TI-89 Titanium, TI-92, TI-92 Plus, Voyage 200 and TI-Nspire series). However, the processor runs at only 2 MHz whereas the other Z80-powered Texas Instruments calculators run at a speed of at least 6 MHz (the TI-83 Plus Silver Edition, TI-84 Plus, and TI-84 Plus Silver Edition run at 15 MHz). It contained 2400 bytes of RAM. The TI-81's user interactions are provided by its so-called Equation Operation System.

It used a system of pulleys and wires to automatically calculate predicted tide levels for a set period at a particular location. The differential analyser, a mechanical analog computer designed to solve differential equations by integration, used wheel-and-disc mechanisms to perform the integration. In 1876 James Thomson had already discussed the possible construction of such calculators, but he had been stymied by the limited output torque of the ball-and-disk integrators.Ray Girvan, "The revealed grace of the mechanism: computing after Babbage" , Scientific Computing World, May/June 2003 In a differential analyzer, the output of one integrator drove the input of the next integrator, or a graphing output.

AC Time to failure LT 100 hours An alternative to graphing the probability that the failure time is less than or equal to 100 hours is to graph the probability that the failure time is greater than 100 hours. The probability that the failure time is greater than 100 hours must be 1 minus the probability that the failure time is less than or equal to 100 hours, because total probability must sum to 1. This gives P(failure time > 100 hours) = 1 - P(failure time < 100 hours) = 1 – 0.81 = 0.19. This relationship generalizes to all failure times: P(T > t) = 1 - P(T < t) = 1 – cumulative distribution function.

Since System 7 was introduced before the Internet came to popular attention, software such as MacTCP, FreePPP and Netscape were not included at first, but was later available on disk from Internet service providers and bundled with books such as Adam C. Engst's Internet Starter Kit for Macintosh. Power Macintosh machines also included NuCalc, a graphing calculator. System 7 also includes AppleTalk networking and file sharing software in the form of system extensions and control panels. The basic utilities installed by default with System 7 include TeachText (which was replaced by SimpleText in later versions) for basic text editing tasks and reading readme documents.

A 24-hour clock displayed on a CRT oscilloscope configured in X-Y mode as a vector monitor with dual R2R DACs to generate the analog voltages Most modern oscilloscopes have several inputs for voltages, and thus can be used to plot one varying voltage versus another. This is especially useful for graphing I-V curves (current versus voltage characteristics) for components such as diodes, as well as Lissajous patterns. Lissajous figures are an example of how an oscilloscope can be used to track phase differences between multiple input signals. This is very frequently used in broadcast engineering to plot the left and right stereophonic channels, to ensure that the stereo generator is calibrated properly.

Casio fx-115ES—A modern scientific calculator from Casio with a dot matrix "Natural Textbook" LCD solar-powered scientific calculator from the 1980s using a single-line LCD A scientific calculator is a type of electronic calculator, usually but not always handheld, designed to calculate problems in science, engineering, and mathematics. They have completely replaced slide rules in traditional applications, and are widely used in both education and professional settings. In certain contexts such as higher education, scientific calculators have been superseded by graphing calculators, which offer a superset of scientific calculator functionality along with the ability to graph input data and write and store programs for the device. There is also some overlap with the financial calculator market.

Graphing the general dispersion curve, a region of propagation occurs from zero up to a lower band edge, followed by a gap, and then an upper passband. The presence of a 400 MHz gap between 4.2 GHz and 4.6 GHz implies a band of frequencies where μeff < 0 occurs. (Please see the image in the previous section) Furthermore, when wires are added symmetrically between the split rings, a passband occurs within the previously forbidden band of the split ring dispersion curves. That this passband occurs within a previously forbidden region indicates that the negative εeff for this region has combined with the negative μeff to allow propagation, which fits with theoretical predictions.

For health care settings like hospitals and clinics, optimum alcohol concentration to kill bacteria is 70% to 95%. Products with alcohol concentrations as low as 40% are available in American stores, according to researchers at East Tennessee State University. Alcohol rub sanitizers kill most bacteria, and fungi, and stop some viruses. Alcohol rub sanitizers containing at least 70% alcohol (mainly ethyl alcohol) kill 99.9% of the bacteria on hands 30 seconds after application and 99.99% to 99.999%Medical research papers sometimes use "n-log" to mean a reduction of n on a (base 10) logarithmic scale graphing the number of bacteria, thus "5-log" means a reduction by a factor of 105, or 99.999% in one minute.

Early in its history, Cemetech became embroiled in drama wrecking the Texas Instruments calculator hobbyist scene, partly stemming from a premature announcement of the Doors CS project. Various community members spoofed user accounts in an attempt to further discredit Cemetech. Cemetech's growth and gradual gain in reputation resolved these initial bumps but in recent years have introduced a tension between the site and fellow community site Omnimaga, occasionally spawning backlash from one or both sites. In early 2011, Cemetech's members took a vocal stand against Texas Instruments' educational division for the TI-Nspire CX graphing calculator to be introduced in Spring 2011, calling on community members to "ignore the Nspire CX and get a [...] Prizm" from TI competitor Casio.

In the case of observed visual binary stars, it is defined as the angular offset of the secondary star from the primary relative to the north celestial pole. As the example illustrates, if one were observing a hypothetical binary star with a PA of 135°, that means an imaginary line in the eyepiece drawn from the north celestial pole to the primary (P) would be offset from the secondary (S) such that the NCP-P-S angle would be 135°. When graphing visual binary orbits, the NCP line is traditionally drawn downward—that is, with north at bottom—and PA is measured counterclockwise. Also, the direction of the proper motion can, for example, be given by its position angle.

When graphing this scenario, essentially we have the same situation as in figure 9, where the arrival curve of vehicles is N1, the departure curve of vehicles absent the bottleneck is N2, and the limited departure curve of vehicles given the bottleneck is N′2. The discharge rate μ is the slope of curve N′2, and all the same traffic flow characteristics as in figure 11 can be determined from this diagram. The maximum delay and maximum queue length can be found at a point M in figure 13 where the slope of N2 is the same as the slope of N′2; i.e. when the virtual arrival rate is equal to the discharge / departure rate μ.

The HP Prime's non-CAS home-screen supports textbook, algebraic and 128-level RPN (aka Advanced RPN) entry logic. However, it uses a new operating system unrelated to HP's legacy Saturn and Saturn-emulated systems, which were used on HP's previous RPN/RPL graphing calculators; therefore, it is not compatible with any User RPL or System RPL, or with programming in Saturn or ARM assembler language. The calculator supports programming in a new, Pascal-like programming language now named HP PPL (for Prime Programming Language, but originally also referred to as HP Basic) that also supports creating apps. This is based on a language introduced on the HP 38G and built on in subsequent models.

In the 1990s, with the advent of TI's graphing calculator series, programming became popular among some students. The TI-8x series of calculators (beginning with the TI-81) came with a built-in BASIC interpreter, through which simple programs could be created. The TI-85 was the first TI calculator to allow assembly programming (via a shell called "ZShell"), and the TI-83 was the first in the series to receive native assembly. Around the same time that these programs were first being written, personal web pages were becoming popular (through services such as Angelfire and GeoCities), and programmers began creating websites to host their work, along with tutorials and other calculator-relevant information.

For a system as slow as a graphing calculator, this is too inefficient for an interpreted language. To increase program speed and coding efficiency, the above line of code would be only three characters. "Disp_" as a single character, "[A]" as a single character, and a newline character. This normally means that single byte chars will query the standard ASCII chart while two byte chars (the Disp_ for example) will build a graphical string of single byte characters but retain the two byte character in the program memory. Many graphical calculators work much like computers and use versions of 7-bit, 8-bit or 9-bit ASCII-derived character sets or even UTF-8 and Unicode.

The topic of complex numbers was also being studied by other mathematicians, notably Carl Friedrich Gauss and Caspar Wessel. Wessel's 1799 paper on a similar graphing technique did not attract attention. Argand is also renowned for delivering a proof of the fundamental theorem of algebra in his 1814 work Réflexions sur la nouvelle théorie d'analyse (Reflections on the new theory of analysis). It was the first complete and rigorous proof of the theorem, and was also the first proof to generalize the fundamental theorem of algebra to include polynomials with complex coefficients. In 1978 it was called by The Mathematical Intelligencer “both ingenious and profound,” and was later referenced in Cauchy's Cours d’Analyse and Chrystal's influential textbook Algebra.

NCO is linked to the market for loanable funds and the international foreign exchange market. This relationship is often summarized by graphing the NCO curve with the quantity of country A's currency in the x-axis and the country's domestic real interest rate in the y-axis. The NCO curve gets a negative slope because an increased interest rate domestically means an incentive for savers to save more at home and less abroad. NCO also represents the quantity of country A's currency available on the foreign exchange market, and as such can be viewed as the supply-half that determines the real exchange rate, the demand-half being demand for A's currency in the foreign exchange market.

The symphony consists of four movements: #Allegro non troppo #Lento #Allegretto quasi animato #Allegro The main theme of the symphony was devised by projecting the outline of mountains at Belo Horizonte, Brazil, onto graph paper and transcribing the result as a melody. Villa-Lobos called this technique milimetrazação (graphing), sometimes rendered in English as "millimetrization" or "milmeterization" . A harmonized version of this melody for piano, together with a similar treatment titled New York Skyline, was initially published in the October 1942 issue of New Music, devoted to works by Brazilian composers . The first movement is in a slightly unconventional sonata-allegro form which, according to the composer's usual methods, omits the second theme from the recapitulation.

Similarly, in the expression language used by Texas Instruments graphing calculators (at least the early models including the TI-81 and TI-82), a raised minus sign is used in negative numbers (e.g., as the result of ). All three uses can be referred to as "minus" in everyday speech, though the binary operator is sometimes read as "take away". In most English-speaking countries, (for example) is normally referred to as "minus five", but in modern US usage, it is instead usually called "negative five"; here, "minus" may be used by speakers born before 1950, and is still popular in some contexts, but "negative" is usually taught as the only correct reading.

In mathematics, the circumflex can signify exponentiation (`3^5` for ), where the usual superscript is not readily usable (as on some graphing calculators). It is also used to indicate a superscript in TeX typesetting. As Isaac Asimov described it in his 1974 "Skewered!" essay (on Skewes' number), "I make the exponent a figure of normal size and it is as though it is being held up by a lever, and its added weight when its size grows bends the lever down." The use of the circumflex for exponentiation can be traced back to ALGOL 60, which expressed the exponentiation operator as an upward-pointing arrow, intended to evoke the superscript notation common in mathematics.

Perhaps the HP-42S was to be released as a replacement for the aging HP-41 series as it is designed to be compatible with all programs written for the HP-41. Since it lacked expandability, and lacked any real I/O ability, both key features of the HP-41 series, it was marketed as an HP-15C replacement. The 42S, however, has a much smaller form factor than the 41, and features many more built-in functions, such as a matrix editor, complex number support, an equation solver, user- defined menus, and basic graphing capabilities (the 42S can draw graphs only by programs). Additionally, it features a two-line dot matrix display, which made stack manipulation easier to understand.

Apple co-founder Steve Wozniak originally designed the Apple I computer while working at HP and offered it to them under their right of first refusal to his work; they did not take it up as the company wanted to stay in scientific, business, and industrial markets. Wozniak said that HP "turned him down five times", but that his loyalty to HP made him hesitant to start Apple with Steve Jobs. The company earned global respect for a variety of products. They introduced the world's first handheld scientific electronic calculator in 1972 (the HP-35), the first handheld programmable in 1974 (the HP-65), the first alphanumeric, programmable, expandable in 1979 (the HP-41C), and the first symbolic and graphing calculator, the HP-28C.

The internal low- to medium-level variant of RPL, called System RPL (or SysRPL) is used on some earlier HP calculators as well as the aforementioned ones, as part of their operating system implementation language. In the HP 48 series this variant of RPL is not accessible to the calculator user without the use of external tools, but in the HP 49/50 series there is a compiler built into ROM to use SysRPL. It is possible to cause a serious crash while coding in SysRPL, so caution must be used while using it. The high-level User RPL (or UserRPL) version of the language is available on said graphing calculators for developing textual as well as graphical application programs.

40- and 53-column views were also available if a larger font was required or to reduce screen memory footprint, and the display would scroll horizontally when narrower than the printed page. InterWord could not use the extra-low-memory teletext mode except for its main menu, and recommended that the machine have Shadow RAM (like the BBC Master) so that screen memory would not be an issue.InterWord manual page 14 Computer Concepts also published a spreadsheet (InterSheet) and graphing package (InterChart), and a database (InterBase). These ROMs could co-operate via their "ROM-Link", together holding up to 16 documents (word, sheet or database) simultaneously in RAM and switching between these on command, provided there was sufficient RAM for the documents.

HP-12C financial calculator including functions to calculate depreciation and net present value. A financial calculator or business calculator is an electronic calculator that performs financial functions commonly needed in business and commerce communities (simple interest, compound interest, cash flow, amortization, conversion, cost/sell/margin, etc.). It has standalone keys for many financial calculations and functions, making such calculations more direct than on standard calculators.. It may be user programmable, allowing the user to add functions that the manufacturer has not provided by default.. Examples of financial calculators are the HP 12C, HP-10B and the TI BA II.. A wide number of graphing calculators, like the Casio FX-9860GII, the Texas Instruments TI-89 Titanium, and the Hewlett Packard HP-48GII include complex financial calculations.

By measuring and graphing, for example, physical and intellectual fatigue, Joteyko argued that military training would produce better results if limited to six months. In studies on workers, she concluded that industry could improve on efficiency and production, as well as the lives of workers, by evaluating the mental and physical fatigue factors involved in various tasks. She suggested basing pay on the effort required to accomplish a job, as a means of equalizing wages for various tasks, rather than basing pay on factors like gender. These studies led her to investigations on children and how educational facilities could apply scientific methods to improve and optimize the potential of their students. In 1911, Joteyko organized and chaired an international Paedological Congress hosted in Brussels.

The researchers then used the simulated data set and the graphical conventions of the behavioral scientists to produce patterns like those described as validating the Dunning–Kruger effect. They traced the origin of the patterns, not to the dominant literature's claimed psychological disposition of humans, but instead to the nature of graphing data bounded by limits of 0 and 100 and to the process of ordering and grouping the paired measures to create the graphs. These patterns are mathematical artifacts that random noise devoid of any human influence can produce. They further showed that the graphs used to establish the effect in three of the four case examples presented in the seminal paper are patterns characteristic of purely random noise.

Miller also told Peters about a book he was writing on a structural and proportional organization of art. It connected to the early meeting and discussions with George Bellows at the Art Institute in 1919. Those conversations about perspective and line value lead him, years later, to experiment with the proportions of classic paintings by graphing circles and lines over reproductions. He was convinced he would eventually introduce a universal theory about extending every line found in a painting. “An artist falls in love with a particular pattern of the universe making harmony of it. Love. That’s the basis of it. There’s a kind of love for the work one is doing that one never outgrows. Age doesn’t dim this enthusiasm.” His wife, Dale, died in 1977.

Examples of horizontal and vertical scrollbars around a text box A scrollbar is an interaction technique or widget in which continuous text, pictures, or any other content can be scrolled in a predetermined direction (up, down, left, or right) on a computer display, window, or viewport so that all of the content can be viewed, even if only a fraction of the content can be seen on a device's screen at one time. It offers a solution to the problem of navigation to a known or unknown location within a two-dimensional information space. It was also known as a handle in the very first GUIs. They are present in a wide range of electronic devices including computers, graphing calculators, mobile phones, and portable media players.

The HP-9100 series was built entirely from discrete transistor logic with no integrated circuits, and was one of the first uses of the CORDIC algorithm for trigonometric computation in a personal computing device, as well as the first calculator based on reverse Polish notation (RPN) entry. HP became closely identified with RPN calculators from then on, and even today some of their high-end calculators (particularly the long-lived HP-12C financial calculator and the HP-48 series of graphing calculators) still offer RPN as their default input mode due to having garnered a very large following. The HP-35, introduced on February 1, 1972, was Hewlett-Packard's first pocket calculator and the world's first handheld scientific calculator.HP-35 Scientific Calculator Awarded IEEE Milestone Like some of HP's desktop calculators it used RPN.

The findings were corroborated in part by a Gallup survey. In McCabe's 2001 of 4500 high school students, "74% said they cheated on a test, 72% cheated on a written work, and 97% reported to at least had copied someone's homework or peeked at someone's test. 1/3 reported to have repeatedly cheated."The Case of the Purloined Paper by Brigid Schulte The new revolution in high-tech digital info contributes enormously to the new wave in cheating: online term-paper mills sell formatted reports on practically any topic; services exist to prepare any kind of homework or take online tests for students, despite the fact that this phenomenon, and these websites, are well known to educators; MP3 players can hold digitalized notes; graphing calculators store formulas to solve math problems.

The "unilateral conduction" of crystals was discovered by Karl Ferdinand Braun, a German physicist, in 1874 at the University of Würzburg. He studied copper pyrite (Cu5FeS4), iron pyrite (iron sulfide, FeS2), galena (PbS) and copper antimony sulfide (Cu3SbS4). This was before radio waves had been discovered, and Braun did not apply these devices practically but was interested in the nonlinear current–voltage characteristic that these sulfides exhibited. Graphing the current as a function of voltage across a contact made by a piece of mineral touched by a wire cat whisker, he found the result was a line that was flat for current in one direction but curved upward for current in the other direction, instead of a straight line, showing that these substances did not obey Ohm's law.

The Hacker's Diet (humorously subtitled "How to lose weight and hair through stress and poor nutrition") is a diet plan created by the founder of Autodesk, John Walker, outlined in an electronic book of the same name, that attempts to aid the process of weight loss by more accurately modeling how calories consumed and calories expended actually impact weight. Walker notes that much of our fat free mass introduces signal noise when trying to determine how much weight we're actually losing or gaining. With the help of a graphing tool (Excel is used in the book), he addresses these problems. Factoring in exercise, and through counting calories, one can calculate one's own total energy expenditure (basal metabolic rate, thermic effect of food, and day-to- day exercise) and cut back calorie intake or increase exercise to lose weight.

Usually these spreadsheet files are distributed via email to colleagues resulting in even more copies of the data roaming through the enterprise. With Microsoft PowerPivot for Microsoft SharePoint, Excel spreadsheets can be distributed as dashboards throughout the entire company, giving even more users the tools to create spreadmarts. The growth of spreadmarts poses tangible risks for companies, since undefined and uncoupled data can be used to draw false conclusions that lead to wrong decisions, which will cost time and money to discover and correct. Although Business Intelligence 2.0 software vendors claim to have overcome this issue, locally installed spreadsheet and graphing software continues to be easier to access and use, giving the business analyst the freedom to create the needed analysis quickly, and choose to live with the risk of data inconsistency that goes with it.

In mid-2006, Cemetech lost several hundred posts when hosting provider Jatol disappeared overnight, stranding hundreds of customers without websites or backups. From 2008, Cemetech expanded further into hardware development, releasing popular projects such as the Clove 2 typing glove, an electro-acoustic musical instrument, and several hardware mods of graphing calculators. Major software projects have included networking libraries for calculators and other low-resource devices, as well as the hardware and computer software to support internet-connected calculators, an extensive shell called Doors CS for these devices, and work on distributed computing and image processing projects by the founder and several staff members. In 2012, Cemetech's founder published a book called "Programming the TI-83 Plus/TI-84 Plus" which was published by Manning Publications, an introductory programming book inspired by his experiences working with beginner programmers at Cemetech.

Casio also makes label printers which can be used with rolls of paper for the Casio BASIC calculators.Casio CFX-9850 PB Users' Manual, Chapter 21 Programs, variables, data, and other items can be exchanged from one calculator to another (via SB-62 cable) and to and from a computer (via USB cable). All new models of Casio graphing calculators have both ports and include both cables. The Casio calculators, as with those of many of the other big three manufacturers' machines, can acquire data from instruments via a data logger to which probes for temperature, light intensity, pH, sound intensity (dBA), voltage and other electrical parameters, as well as other readings, and custom probes to attach to the data logger Casio CFX-9850 PB Users' Manual, Chapter 17 can be built and configured for use with the data logger and calculator.

The TI-82 is powered by the same processor that powered its cousin, the TI-85, a 6 MHz Zilog Z80 microprocessor. This was an improvement over the TI-81's 2 MHz Z80 processor. In addition, the available RAM was increased more than tenfold – from 2400 bytes to 28734 bytes (slightly more than the TI-85). Some of the more notable improvements of the TI-82 over the TI-81 include the following: the addition of a link port to enable programs and other data to be transferred between two calculators or between a calculator and a computer; the addition of two new graphing types – polar and sequence, the addition of a new type of data – the list, the expansion of the size limit of matrices to 50x50, and the (unintentional) addition of the ability to program the calculator in assembly language.

Companies take different attitudes towards such practices, ranging from open acceptance (such as Texas Instruments for its graphing calculators and Lego for its Lego Mindstorms robotics gear) to outright hostility (such as Microsoft's attempts to lock out Xbox hackers or the DRM routines on Blu-ray Disc players designed to sabotage compromised players.) In this context, a "hack" refers to a program that (sometimes illegally) modifies another program, often a video game, giving the user access to features otherwise inaccessible to them. As an example of this use, for Palm OS users (until the 4th iteration of this operating system), a "hack" refers to an extension of the operating system which provides additional functionality. Term also refers to those people who cheat on video games using special software. This can also refer to the jailbreaking of iPhones.

Implementations that share the familiar Citadel user interface, but are not derived from the original Citadel code base, are also common. They have ranged from vanity projects such as a Citadel-like control program to control the serial port of an advanced graphing calculator, to full-blown efforts to modernize the Citadel interface with modern protocols. Some of the more notable ones included Glenn Gorman's TRS-80 BASIC implementation called Minibin, a clone of Cit-86 intended to run on a Unix running on Motorola processors called Cit/68, and a Unix version, technically called Citadel/UX but referred to simply as "Citadel" in the mainstream open source community. This version of Citadel is still being developed, extending the Citadel metaphor to enable what its developers call "a messaging and collaboration platform (for) connecting communities of people together": a groupware platform.

In 2015, CNN used the queastion "Is this the next da Vinci?" for the title of a video about Naderi Yeganeh's work and RT en Español used the question "New da Vinci?" at the beginning of the title of an article about him and Al Arabiya used this question for the article about Naderi Yeganeh: "Is this Iranian student da Vinci's successor?". And Iranian media such as IRNA and Isfahan Ziba titled him as "The Iranian da Vinci" and "Iran's da Vinci" in their articles about Hamid Naderi Yeganeh. In 2015, The National Museum of Mathematics stated in a post on Facebook that "Hamid Naderi Yeganeh takes graphing art to the next level!" In 2016, Institute for Mathematics and its Applications commented on the Naderi Yeganeh's blog post showing how to draw human faces with mathematical equations: "Another reason that math wins".

As the graphic includes red concentric circles denoting temperature changes of 1.5°C and 2.0°C, Hawkins explained that "the relationship between current global temperatures and the internationally discussed target limits is also clear without much complex interpretation needed". Ria Misra wrote in Gizmodo that the graphic "lets the noise of tiny variations fade into the background while still showcasing, very simply, the undeniable trend". Describing how global warming "appears to burst outward toward the end of the animation", Hawkins described how sulfate aerosols no longer counteracted the warming effect greenhouse gases after the 1970s, and noted how strong El Niño events in 1998 and 2016 lead to higher temperature plateaus more recently. The first climate spiral portrayed data from HadCRUT4.4 from January 1850 – March 2016, graphing relative to the 1850-1900 mean temperature, the same pre-industrial global average used in the IPCC Fifth Assessment Report.

A DIY musician probes the circuit board of a synthesizer for "bends" using a jeweler's screwdriver and alligator clips Electronics hobbyists working on machines other than computers also fall into this category. This includes people who do simple modifications to graphing calculators, video game consoles, electronic musical keyboards or other device (see CueCat for a notorious example) to expose or add functionality to a device that was unintended for use by end users by the company who created it. A number of techno musicians have modified 1980s-era Casio SK-1 sampling keyboards to create unusual sounds by doing circuit bending: connecting wires to different leads of the integrated circuit chips. The results of these DIY experiments range from opening up previously inaccessible features that were part of the chip design to producing the strange, dis-harmonic digital tones that became part of the techno music style.

"Bad Apple!!" is the seventh track in the soundtrack of the 1998 bullet hell video game Lotus Land Story, the fourth entry in the Touhou Project series created by Team Shanghai Alice. The theme was originally designed to be played during the third stage of the game, as chiptune on the Japanese NEC PC-9800 computer platform, at 161 beats per minute using a frequency modulation synthesis chip. It is notable for leading to a much later remix by and singer Nomico and following the remix a subsequent accompanying black-and-white shadow puppet-video. In the 2010s, the version sung by Nomico and the black- and-white video sequence were ported to several second-generation video game consoles and graphing calculators, for retrocomputing and Demoscene competitions, becoming a graphical equivalent to the "Hello, World!" programs of older computer systems in the demoscene communities.

The 1801 series CPUs were a family of 16-bit Soviet microprocessors based on the indigenous Elektronika NC microarchitecture cores, but binary compatible with DEC's PDP-11 machines. First released in 1980, various models and variants of the series were among the most popular Soviet microprocessors and dominated embedded systems and military applications of the 1980s. They were also used in widely different areas such as graphing calculators (Elektronika MK-85) and industrial CNCs (Elektronika NC series), but arguably their most well-known use was in several Soviet general-purpose mini- and microcomputer designs like the SM EVM, DVK, UKNC, and BK families. Due to being the CPU of the popular Elektronika BK home computer, used in its late years as a demo machine, as well as the DVK micros that often offered a first glimpse into the UNIX world, this processor achieved something of a cult status among Soviet and then Russian programmers.

Multiplication symbols are usually omitted, and implied when there is no space between two variables or terms, or when a coefficient is used. For example, 3 \times x^2 is written as 3x^2, and 2 \times x \times y may be written 2xy.Sin Kwai Meng, Chip Wai Lung, Ng Song Beng, "Algebraic notation", in Mathematics Matters Secondary 1 Express Textbook, Publisher Panpac Education Pte Ltd, , 9789812738820, page 68 Usually terms with the highest power (exponent), are written on the left, for example, x^2 is written to the left of .

Since then Sharp's innovations include models with a touchscreen (EL9600 series), Equation Editor (textbook-like input) (EL-9300 ( 1992 ) and later), and reversible keyboard to ease learning (one side has basic functions, the other side has additional functions) (March 2005, EL-9900). Hewlett Packard followed in the form of the HP-28C. This was followed by the HP-28S (1988), HP-48SX (1990), HP-48S (1991), and many other models. Models like the HP 50g (2006) or the HP Prime (2013) feature a computer algebra system (CAS) capable of manipulating symbolic expressions and analytic solving. An unusual and powerful CAS "calculator" is the now obsolete year 2001 Casio Cassiopeia A-10 and A-11 (flip top) stylus-operated PDAs, which ran the Maple V symbolic engine. The HP-28 and -48 ranges were primarily meant for the professional science/engineering markets; the HP-38/39/40 were sold in the high school/college educational market; while the HP-49 series cater to both educational and professional customers of all levels. The HP series of graphing calculators is best known for its Reverse Polish notation (RPN) / Reverse Polish Lisp (RPL) interface, although the HP-49G introduced a standard expression entry interface as well.
