WebIn mathematics, de Moivre's formula (also known as de Moivre's theorem and de Moivre's identity) states that for any real number x and integer n it holds that (⁡ + ⁡) = ⁡ + ⁡,where i is the imaginary unit (i 2 = −1).The formula is named after Abraham de Moivre, although he never stated it in his works. The expression cos x + i sin x is sometimes abbreviated to cis x.
