## What is a polar equation?

Polar Equations A polar equation is any equation that describes a relation between r r r and θ theta θ, where r r r represents the distance from the pole (origin) to a point on a curve, and θ theta θ represents the counterclockwise angle made by a point on a curve, the pole, and the positive x x x-axis.
