**De Moivre's Theorem**

De Moivre's Theorem is a relatively simple formula for calculating powers of complex numbers.

De Moivre's formula states that for any real number x and any integer n,
(cosx + isinx)^{n} = cos(nx) + isin(nx).

Often abbreviated to:

If *n is any integer then *

*
(r cisθ)^{n} = r^{n} cis(nθ) *
