# Coordinate System - Polar Coordinate System

Another common coordinate system for the plane is the Polar coordinate system. A point is chosen as the pole and a ray from this point is taken as the polar axis. For a given angle θ, there is a single line through the pole whose angle with the polar axis is θ (measured counterclockwise from the axis to the line). Then there is a unique point on this line whose signed distance from the origin is r for given number r. For a given pair of coordinates (r, θ) there is a single point, but any point is represented by many pairs of coordinates. For example (r, θ), (r, θ+2π) and (−r, θ+π) are all polar coordinates for the same point. The pole is represented by (0, θ) for any value of θ.

### Famous quotes containing the words system and/or polar:

Books are for the most part willfully and hastily written, as parts of a system to supply a want real or imagined.
Henry David Thoreau (1817–1862)

In time your relatives will come to accept the idea that a career is as important to you as your family. Of course, in time the polar ice cap will melt.
Barbara Dale (b. 1940)
