{\em Grapher} is a software graphing calculator that comes bundled with the Apple Mac OS Xoperating system. It can graph 2-dimensional equations like $y = \sin x$, as well as 3-dimensional equations like $z = \frac{y^3}{x^2 + y^2}$ (Cartan's umbrella, illustrated below).

Equations to be graphed can be entered in Cartesian form or in parametric form, polar coordinates, logarithmic, etc. The program automatically ``typesets'' the formulas as they are entered, for example, converting \verb=x^2= to $x^2$ or \verb=1/x= to $\frac{1}{x}$. The program can create animations, and one can also move a graph or rotate it (just by dragging it, for 3D graphs; for 2D graphs one must first select the Move Tool).

In a default installation, the program is in the Utilities subfolder of the Applications folder. Mac OS 9 had a similar program, called Graphing Calculator, which was also capable of graphing 2D and 3D equations as well as animations.
