Graphing Calculator

Graphing Calculator (also known as NuCalc) is the name of a computer software tool, developed by Ron Avitzur of Pacific Tech with the assistance of Greg Robbins. It is capable of performing many scientific calculator functions with graphing capabilities. It can graph inequalites and vectors, as well as functions in two, three, or four dimensions. It supports several different coordinates, and can solve equations. It is available for classic Mac OS as "Graphing Calculator" and Microsoft Windows as "NuCalc".

History
Graphing Calculator 1.0 was bundled for free with all Power Macintosh computers since their introduction in March 1994. Hence, it was shipped on more than 20 million computers, and is the most familiar version of the program. NuCalc was sold separately for older 68k Macintosh systems and Windows.

Later models of Power Macintosh computers included newer versions of the Graphing Calculator program. The latest free version available on the website is Graphing Calculator 1.4, which could be run under the Classic environment of Mac OS X. However, these versions lacked some of the features of the original 1.0 version, and promoted a more advanced commercial version of the software, like a demo. The latest commercial version is Graphing Calculator 4. This version does not have a demo counterpart; a viewer app without input capabilities is the only freely downloadable version available.

Grapher, a new replacement for Graphing Calculator, was included with since Mac OS X 10.4. This version was based on Curvus Pro X, which Apple had acquired from Arizona Software on July 22, 2004.
