Chapter 14:
3D Graph Application
The 3D Graph application lets you draw a 3-dimensional graph of an
equation in the form z = f (x, y) or of a parametric equation.
The 3D Graph application has a 3D Graph Editor window (1) and a 3D
Graph window (2). Functions you input on the 3D Graph Editor window
are graphed on the 3D Graph window. You can select any one of the
expressions on the 3D Graph Editor window and graph it on the 3D Graph
window.
