Operation Manual

Example

Convert polar coordinates (r, q)=(5, 30) into rectangular

coordinates. Then convert rectangular coordinates

(x, y) = (3, 4) into polar coordinates. Round the results to one

decimal place.

Converting (r,

q) = (5, 30) gives (x, y) = (4.3, 2.5) and

(x, y) = (3, 4) gives (r,

q) = (5.0, 53.1).
