# Coordinates

Robert P. Munafo, 1999 Feb 2.

The coordinates of a point can be given in two ways — orthogonal and polar.

In orthogonal coordinates, there is a real coordinate commonly referred to as a and an imaginary coordinate commonly referred to as b i.

In polar coordinates there is a radius and an angle.
