GraphCalc
GraphCalc is an open-source computer program that runs in Microsoft Windows and Linux that provides the functionality of a graphing calculator.
GraphCalc includes many of the standard features of graphing calculators, but also includes some higher-end features:
GraphCalc was developed by Brendan Fields and Mike Arrison, computer science students at Bucknell University, before graduating in 2000. Mike continued the development briefly from 2001-2003, but has since abandoned the project. Other similar projects being maintained are KAlgebra and Cantor.
