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 executingthe complexoperation, then convert the
result back to polar form.
