Open Source Windows Graphing Calculators

TILP (formerly GtkTiLink) can transfer data between Texas Instruments graphing calculators and a computer. It works with all link cables (parallel, serial, Black/Gray/Silver/Direct Link) and it supports the TI-Z80 series (73..86), the TI-eZ80 series (83PCE, 84+CE), the TI-68k series (89, 92, 92+, V200, 89T) and the Nspire series (Nspire Clickpad / Touchpad / CX, both CAS and non-CAS). The project is now managed on Github, https://github.com/debrouxl/tilp_and_gfm . It uses the libti* libraries, https://github.com/debrouxl/tilibs . Install script for *nix: https://github.com/debrouxl/tilp_and_gfm/blob/master/tilp/trunk/build/scripts/install_tilp.sh

GraphCalc is a very gui graphing calculator. It has been called a good replacement for a TI-85. It is a must for any high school math student.

Photon is a fully functional graphing calculator capable of numeric calculations as well as graphing functions, including parametric and polar graphs. In addition to regular graphing, Photon can plot integrals, first and second derivatives, tracing, animation, matrix math, and degree / radian mode. Photon can find roots, minimums and maximums, points of inflection, and it can fit several types of best fit lines and curves to data sets. Log and semi-log graphing are also available. Photon can save data to several file types, including images such as .jpg and .png. Display options are also available, including a dark / light theme for optimal visibility from a projector. Photon's primary goal is to be easy to use while retaining a feature-rich design. VB Gadgets brings you Photon - a parametric graphing calculator.

A cross-platform, text-interpreting calculator written in the Java programming language. Runs on any computer with Java 6 or higher installed. Functions much like a Ti-84, but without the graphing utility.

Calculator for complex numbers: addition, subtraction, multiplication and division with complex numbers. This calculator lets you calculate in an easy and fast way the operations between two complex numbers. It also shows the plots of the source numbers and the results. It shows also the quadrants, the magnitudes, and the angles of all the numbers involved. You just put your two numbers and all the calculations will be done!!! As easy like that!!!

The Revolution-FX project goal is to provide the best platform for developing applications for the CASIO fx-9860G graphing calculator. Revolution-FX components include addheader, code editor, a hardware library, and works with the GNU toolchain.

Direct link to source code: http://sourceforge.net/projects/consolegrapher/files/Source/ConsoleGrapher_Source.zip/download . Just what you needed: a simple, down-to-earth two dimensional graphing calculator inside the elegance of the Windows console! This is a program that I wrote as a method for mastering the C# programming language. Though the features are not what you would expect from a program written and sold by a corporation, you may find it an entertaining tool Also notice that no installation is required, meaning it will not put annoying icons on your desktop and start menu, and you are free to delete it at will. If you know coding, be sure to check out the source code, which is in the form of a zipped-up Visual Studio solution. If you would like to import some of the functions into your own project, the code is free to be used.

A 3d/2d Graphing Calculator with multiple tools, written in C# for Microsoft Windows. DirectX9.0c with Mananged Extentions and the .Net 2.0 Framework are required to run this program. It uses the freely availible Lundin Math Parser, www.lundin.info.
