Question

Sate de moiver's theoram​

Answer 1

Explanation:

For any complex number x and any integer n, ( r ( cos ⁡ θ + i sin ⁡ θ ) ) n = r n ( cos ⁡ ( n θ ) + i sin ⁡ ( n θ ) )

Answer 2

Explanation:

In mathematics, de Moivre's formula states that for any real number x and integer n it holds that where i is the imaginary unit. 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).
