... the number z = | z | (cosϕ + isinϕ), then multiplying it. by itself n times (which is equivalent to raising it.to the power n), we get :. zn = (| z | (cosϕ + isinϕ)) n = | z | n (cosnϕ + isinnϕ). Thus , the modulus of a complex number is equal to. the same exponent of the modulus of the base , and.the argument ... ... , and.the argument is equal to the argument of the base multiplied . by the exponent If | z | = 1 , then we obtain that zn = (cosϕ + isinϕ) n = cosnϕ + isinnϕ This formula is called the Moivre formula (Abraham de Moivre .
