To graph parametric equations, use the same general steps used for y(x) functions as
described in Basic Function Graphing. Any differences that apply to parametric
equations are described on the following pages.

1. Set Graph mode ( 3) to
PARAMETRIC .
Also set Angle mode, if necessary.
2. Define x and y components on Y= Editor
( 8 #).
3. Select ( †), which defined equations to
graph. Select the x or y component, or
both.
