I am new to this forum as my post counter will show, and I have a toughy right out of the box. Can someone please point me in the right direction?
I am a little fuzzy on this as I have not been in school for 20 years.
Goes to show how much we use this junk huh?
DeMoivre’s Theorem states, “If z = r(cos u + i sin u), then zn = rn(cos nu + i sin nu).”
I have to verify for n=2. Where the heck am I supposed to start?
I do not remember DeMoivre's Theorem.
Any help would be greatly appreciated.
