Understanding De Moivre's Theorem

De Moivre's theorem states that for a complex number z = r(cosθ + i·sinθ), the nth power is z^n = r^n(cos(nθ) + i·sin(nθ)). This elegant formula connects complex arithmetic to trigonometry and makes computing powers and roots of complex numbers straightforward using polar form.
