Using Complex Numbers in Polar Notation

Many applications use real numbers in polar form or polar notation. These forms
use pairs of numbers, as do complex numbers, so you can do arithmetic with these
numbers by using the complex operations. Since the HP 33s's complex operations
work on numbers in rectangular form, convert polar form to rectangular form

Example:
Vector Addition.
Add the following three loads. You will first need to convert the polar coordinates
to rectangular coordinates.
