Expert Answer:

Answer : The polar coordinate system is a two-dimensional coordinate system in which each point on a plane is determined by a distancefrom a fixed point and an angle from a fixed direction.

The fixed point (analogous to the origin of a Cartesian system) is called the pole, and the ray from the pole in the fixed direction is the polar axis. The distance from the pole is called the radial coordinate or radius, and the angle is the angular coordinate, polar angle.

The radial coordinate is often denoted by r, and the angular coordinate by theta or t.

Angles in polar notation are generally expressed in either degrees or radians
