• Rectangular-Polar Coordinate Transformation (REC, POL)
Here
e
of polar coordinates (r, 8) is assumed to be obtained in radians.
Example:
The point (5, rr/6) in the polar coordinate is (4.330127019, 2.5) in the rec-
tangular coordinate.

In these functions, results are assigned to variables X and Y. Output values are
the same as the content of variable X.
*
In these functions , angle unit specification is as important as in the case of
trigonometric or inverse trigonometric functions.
