# Grapher

Grapher is a software graphing calculator that comes bundled with the Apple Mac OS Xoperating system. It can graph 2-dimensional equations like $y=\mathrm{sin}x$, 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 `x^2`

to ${x}^{2}$ or `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.
