Convert z = 12cos12° + 12isin12° from polar form to rectangular form.

But z is already given in rectangular form... A complex number in rectangular form looks like , where .

Perhaps you're supposed to write cos(12º) and sin(12º) in non-trigonometric form? In that case, we want exact forms of these numbers.

Note that 12º = 60º/5. Consider the identities

(both of which follow from DeMoivre's theorem)

We have and , so we get
