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).

%%discuss effects of multiplication on angle and radius, etc.
