Remarks:
Converts numeric arguments
of
rectangular
coordinates to
their
polar
coordinate equivalents.
The first argument indicates the distance from the y-axis
and the second the distance from the x-axis. The
values
converted indicate the distance from the origin and the
angle
in the
polar
coordinates, and are assigned to the
fixed
variables
Y
