Question

Application of de-moive theorem​

Answer 1

Step-by-step explanation:

De Moivre's theorem gives a formula for computing powers of complex numbers. We first gain some intuition for de Moivre's theorem by considering what happens when we multiply a complex number by itself. This shows that by squaring a complex number, the absolute value is squared and the argument is multiplied by 2.

Answer 2

Answer:

De-Moivre's Theorem: A simple formula for calculating powers of complex numbers in the form of cosθ and sinθ is known as de-Moivre's theorem. If n is a rational number, then (cosθ + sinθ)ⁿ = cos nθ + i sin nθ. Applications of De-Moivre's Theorem: ... 1/ (cosθ + i sinθ) = (cosθ + i sinθ)⁻¹ = cosθ – i sinθ17-
