When you press s, the TI-84 Plus plots the selected polar equations. It evaluates R
for each value of q (from q
min 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.
