The steps for defining a polar graph are similar to the steps
for defining a function graph. Chapter 5 assumes that you
are familiar with Chapter 3: Function Graphing. Chapter 5
details aspects of polar graphing that differ from function
graphing.
To display the mode screen, press z. To graph polar
equations, you must select Pol graphing mode before you
enter values for the window variables and before you enter
polar equations.
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 (page 5.4).
The icons to the left of r1 through r6 represent the graph
style of each polar equation (Chapter 3). 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.
