3D Graphing

Overview of Steps in Graphing 3D Equations

To graph 3D equations, use the same general steps used for

y(x)

functions as described

in Basic Function Graphing. Any differences that apply to 3D equations are described on
the following pages.

Graphing 3D Equations

1. Set Graph mode (

3) to

. Also set

Angle

mode, if necessary.

2. Define 3D equations on Y= Editor

(

8 #).

3. Select (

†) which equation to graph. You

can select only one 3D equation.

To turn off any stat data plots, press

4. Define the viewing cube (

8 $).

For 3D graphs, the viewing window is
called the viewing cube.
