Defining a Polar Graph

The steps for defining a polar graph are similar to the steps for defining a function graph. This
chapter assumes that you are familiar with Chapter 5: Function Graphing and Chapter 6:
Graph Tools. Chapter 8 details aspects of polar graphing that differ from function graphing.

Setting Polar Graphing Mode

To display the mode screen, press - m. To graph polar equations, you must select
graphing mode before you enter equations, set the format, or edit window variable values. The
TI-86 retains separate equation, format, and window data for each graphing mode.
