Analytic Geometry in Polar Coordinates

Analytic Geometry in Polar Coordinates represents a system in which every point on a plane is determined by its distance from a fixed point and the angle it forms with a predetermined direction. This system proves to be extremely beneficial when dealing with problems that require an understanding of distances and angles, such as those found in the fields of physics and engineering.

Converting to Polar Coordinates

Suppose a point has polar coordinates (−6,−2π3), with the angle measured in radians. Find two additional polar representations of the point. Write each coordinate in simplest form with the angle in [−2π,2π].
