Grapher is a free tool bundled with Mac OS X (10.4+) that enables graphing and analyzing implicit and explicit equations in two or three dimensions. The results can be visualized as an animation or image. 
Grapher is a graphing calculator, capable of creating both 2-D graphs including classic (linear-linear), polar coordinates, linear-logarithmic, log-log, and polar log as well as 3-D graphs including standard system, cylindrical system, and spherical system.
You can find Grapher in the Utilities folder within the Applications folder. The easiest way to launch Grapher, though, is using Spotlight.
New Graph
To use Grapher, first choose the type of graph you want to create. You can select from a variety of 2-D and 3-D templates. Choose New Equation to create your own equation, or choose New Equation From Template to add parametric equations, differential equations, vector field equations, or series from templates. Select an equation in the equations list to edit or delete the equation.
Grapher supports multiple equations in one graph, exporting equations to LaTeX format, and includes several pre-made equation examples. It is capable of easily exporting vector art for use in printed documents. QuickTime animation of graphs is also supported in both 2-D and 3-D.

Grapher’s equation menu includes functions for evaluating equations, performing integration, and finding intersections. You can click any point of an equation to view its evaluation or find an approximate intersection.
