Polar/Rectangular Coordinate
Conversion
Two function s are provided for polar/rectangular coordinate
conversion . To convert values in the X-and Y- registers, (repre-
senting rectangul ar x, y coordinates , respectively) to polar r,
(J
coordinates (magnitude and angle , respectively) , press
m ~ .
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,
(J ,
respectively) to rectangular coordinates (x , y
respectively), press
0.
Example 1:
Co nvert rectangular coordinates (4,3) to polar form
with the angle expressed in radian s.
