RectGC (rectangular graphing coordinates) displays the cursor location as rectangular
coordinates X and Y.
PolarGC (polar graphing coordinates) displays the cursor location as polar coordinates R
and q.
The
RectGC/PolarGC setting determines which variables are updated when you plot the
graph, move the free-moving cursor, or trace.
