The polar form for complex numbers allows us to graph complex numbers given an angle and a radius or magnitude
.
For , we can write
. (See cis if you do not understand this notation.) This represents a complex number
that is
units away from the origin, and
radians counterclockwise from the positive half of the
-axis.
