Rectangular /Polar
%^ displays a menu to convert rectangular
coordinates (x, y) to polar coordinates (r, æ) or vice
versa. For each coordinate to which you are converting,
enter both values expressed in the format
from which
you are converting, separated by a comma, then close
the parentheses with
O before you complete the
operation with V. Set angle mode, as necessary,
before starting calculations.
³ Examples
Convert polar coordinates (r, æ)=(5, 30) into rectangular
coordinates. Then convert rectangular coordinates
(x, y)=(3, 4) into polar coordinates. Round all results to
1 decimal place.

(r, q)=(5, 30) converts to (x, y)=(4.3, 2.5). (x, y) = (3, 4)
converts to (r, q)=(5.0, 53.1).
