Polar Coordinates

The polar coordinate system is a two-dimensional coordinate system in which each point on a plane is determined by a distance from a reference point and an angle from a reference direction.
The reference point (analogous to the origin of a Cartesian coordinate system) is called the pole, and the ray from the pole in the reference direction is the polar axis. The distance from the pole is called the radial coordinate or radius, and the angle is called the polar angle.
The radial coordinate is often denoted by r and the polar angle by ?.
Converting between polar and Cartesian coordinates
The polar coordinates r and ? can be converted to the Cartesian coordinates x and y by using the trigonometric functions sine and cosine:
x=r cos?? and y=r sin??
The Cartesian coordinates x and y can be converted to polar coordinates r and ? by:
r=?(x^2+y^2 ) and ?=tan^(-1)??( y )/( x )?
