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 Obefore 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).
