Parametric Graphing

Overview of Steps in Graphing Parametric

Equations

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.

Graping Parametic Equations

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.
