Coordinate Conversions

The function names for these conversions are y,x
Polar coordinates (r ,

or between –200 and 200 grads.
To convert between rectangular and polar coordinates:
1. Enter the coordinates (in rectangular or polar form) that you want to convert. In
RPN mode, the order is y
2. Execute the conversion you want: press
º ±
and Y–registers.
3. The resulting display (the X–register) shows either r (polar result) or x
(rectangular result). Press
