MathGrapher is now freeware!!

A mathematical graphing tool for students, scientists and engineers. Draw and analyse Functions and Data in 2D and 3D. Draw surface graphs, contour plots and cross-sections through contour plots. Includes linear and nonlinear curve fitting, integration and analysis of coupled ordinary differential equations, iteration and analysis of multi-dimensional maps, matrix operations, Lindenmayer systems and some cellalar automata.

Mathgrapher contains many demonstrations covering most of the things you can do with it. Just start a demonstration, lean back and see what Mathgrapher can do for you:
