After selecting Pol graphing mode, press
o to display the polar Y= editor.
In this editor, you can enter and display up to six polar equations, r1 through r6 . Each is
defined in terms of the independent variable q.

The icons to the left of r1 through r6 represent the graph style of each polar equation.
The default in Pol graphing mode is
ç (line), which connects plotted points. Line,
è (thick), ë (path), ì (animate), and í (dot) styles are available for polar graphing.
