Displaying a Graph
When you press s, the TI-83 Plus plots the selected polar
equations. It evaluates R for each value of q (from qmin to qmax in
intervals of qstep) and then plots each point. The window variables define
the viewing window.
As the graph is plotted, X, Y, R, and q are updated.
Smart Graph applies to polar graphs (Chapter 3).
