point P on a plane is determined by a distance r from a θ point O that is called the pole (or origin) and an angle from a θ direction. The point P is represented by the ordered pair (r; θ ) and r; θ are called polar coordinates.

The polar coordinate system is a two-dimensional coordinate system in which each
point P on a plane is determined by a distance r from a θ point O that is called the pole (or origin) and an angle from a θ direction. The point P is represented by the ordered pair (r; θ ) and r; θ are called polar coordinates.
