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)

Often abbreviated to:

If

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 cisÎ¸)*^{n}= r^{n}cis(nÎ¸)
