Could someone explain to me how, (De Moivre's Theorem) r(cosx + isinx) is in polar form? This makes no sense to me. At all. I thought polar form was in the form (r, θ), where R is the radius from the origin of some point and theta is the angle from the positive x-axis. I keep seeing the above referred to as in "polar form", but it seems nothing but.
