This is a very terse review of their most important properties. An
arbitrary complex number can be written as:

where
,
, and
. *All complex numbers* can be written as a real amplitude
times a complex exponential form involving a phase angle. Again,
it is difficult to convey how incredibly useful this result is without
further study, but I commend it to your attention.
