83 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 (Chapter 3).
You can perform these actions from the home screen or a
