Polar to rectangular equation conversion

Learn how to convert between rectangular and polar equations. A rectangular equation is an equation having the variables x and y which can be graphed in the rectangular cartesian plane. A polar equation is an equation defining an algebraic curve specified by r as a function of theta on the polar coordinates system.

To convert from rectangular equation to polar equation, we replace x with rcos(theta) and replace y with rsin(theta) where r is given by the square root of the sum of the squares of a and b. And theta is the arctan of the quotient, y / x.
