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.

A = P-Q
(sin T) (|P|+|Q|)/2
