Solver: an interactive expression solver which can, in theory, numerically solve any equation versus any variable, using Newton's method. It may however fail to solve certain classes of equations depending on the expression format and starting values of the variables, so it is often necessary to rewrite the expression or experiment with initial ...
Programmable calculators allow the user to write and store programs in the calculator in order to solve difficult problems or automate an elaborate procedure. Programming capability appears most commonly (although not exclusively) in graphing calculators , as the larger screen allows multiple lines of source code to be viewed simultaneously (i ...
Personal computers often come with a calculator utility program that emulates the appearance and functions of a calculator, using the graphical user interface to portray a calculator. Examples include the Windows Calculator, Apple's Calculator, and KDE's KCalc. Most personal data assistants (PDAs) and smartphones also have such a feature.
Texas Instruments TI-84 Plus, the most successful graphing calculator in terms of sales. A graphing calculator (also graphics calculator or graphic display calculator) is a handheld computer that is capable of plotting graphs, solving simultaneous equations, and performing other tasks with variables.
The simplest example given by Thimbleby of a possible problem when using an immediate-execution calculator is 4 × (−5). As a written formula the value of this is −20 because the minus sign is intended to indicate a negative number, rather than a subtraction, and this is the way that it would be interpreted by a formula calculator.
All the models above support Direct Algebraic Logic (D.A.L.), which is an infix input system used by Sharp similar to Casio's V.P.A.M. EL-501W does not support D.A.L., and only has the 7-segment digit line in EL-509W. It only supports 8-digit mantissa display in scientific notation mode. Functions are further stripped down from EL-500W.
The magnetic program cards are fed in at the thick end of the calculator under the LED display. The documentation for the programs in the calculator is very complete, including algorithms for hundreds of applications, including the solutions of differential equations, stock price estimation, statistics, and so forth.
The Sharp PC-1403 was a small scientific calculator and pocket computer manufactured by Sharp. It was the successor of the Sharp PC-1401 , and had better display, more RAM and better system software.
