Polar Coordinate System
Robert P. Munafo, 1999 Feb 2.
Polar coordinates, based on an angle and a radius, are used as an alternative to simple X and Y coordinates when dealing with certain applications that require specifying locations on the Complex plane.
Consider a point P = a + bi shown here on the complex plane:
: b .P : ..'' : ..'' .........+.::.........a.. :The distance from the origin to P is the radius and is also the absolute value of the complex number P. The absolute value, signified by P, is sqrt(a2 + b2).
