Polar/Rectangular Coordinate
Conversion
Two functions are provided for polar/rectangular coordinate
conversion. To convert values in the X-and Y-registers, (repre-
senting rectangular X, y coordinates, respectively) to polarr,
6 coordinates (magnitude and angle, respectively), press El [+7].
Magnitude r then appears in the X-register and angle is placed
in the Y-register.
Conversely, to convert values in the X-and Y-registers (repre-
senting polar r, 6, respectively) to rectangular coordinates (x, y
respectively), press [
.
Example 1: Convert rectangular coordinates (4,3) to polar form
with the angle expressed in radians.
