Using Complex Number 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 32SII's
complex operations work on numbers in rectangular form, convert polar form
to rectangular form (using
{r before executing the complex
operation, then convert the result back to polar form.
a + i b = r (cos θ + i sin θ) = re i θ
= r ∠ θ (Polar or phasor form)
r
real
(a, b)
imaginary
