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

q

max

in intervals of

q

step

) 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.
