Overview of Steps in Graphing Polar Equations

To graph polar equations, use the same general steps used for

y(x)

functions as

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

Graphing Polar Equations

1. Set

Graph

mode (

3) to

POLAR

. 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.
