The conversion from polar coordinates to rectangular coordinates involves using the sine and cosine functions to find x and y. Polar coordinates are very similar to the "usual" rectangular coordinates: both systems are two dimensional, they locate a point in space, and both use two points: the rectangular system uses (x, y) and the polar coordinate system uses (r, θ). developed with the support of the.
