&amp;#039;&amp;#039;&amp;#039;GraphCalc&amp;#039;&amp;#039;&amp;#039; is an [[open-source software|open-source]] computer program that runs in [[Microsoft Windows]] and [[Linux]] that provides the functionality of a [[graphing calculator]].&lt;br /&gt;
&lt;br /&gt;
GraphCalc includes many of the standard features of graphing calculators, but also includes some higher-end features:&lt;br /&gt;
* High resolution&lt;br /&gt;
** Graphing calculator screens have a resolution typically less than 120×90 pixels, whereas computer monitors typically display 1280x1024 pixels or more.&lt;br /&gt;
* Speed&lt;br /&gt;
** Modern computers are considerably faster than handheld graphing calculators&lt;br /&gt;
* Three-dimensional graphing&lt;br /&gt;
** While high-end graphing calculators can graph in 3-D, GraphCalc benefits from modern computers&amp;#039; memory, speed, and graphics acceleration ([[OpenGL]])&lt;br /&gt;
&lt;br /&gt;
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&amp;amp;ndash;2003, but has since abandoned the project. Other similar projects being maintained are KAlgebra and Cantor.&lt;br /&gt;
