Using Numbers in Polar Notation
Many applications use real numbers in polar form or phasor notation.
These forms use pairs of numbers, as do complex numbers, so you
can do arithmetic with these numbers by using the complex opera
tions. Since the HP-32S's complex operations work on numbers in
rectangular form, convert polar form to rectangular form (using
111 p~REcf"|) before executing the complex operation, then convert the
result back to polar form.
a + to = r(cos 0 + i sin 6) = rei$

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