WebJan 2, 2024 · De Moivre’s Theorem. The result of Equation 5.3.1 is not restricted to only squares of a complex number. If z = r(cos(θ) + isin(θ)), then it is also true that. z3 = zz2 = (r)(r2)(cos(θ + 2θ) + isin(θ + 2θ)) = r3(cos(3θ) + isin(3θ)) We can continue this pattern to see that. z4 = zz3 = (r)(r3)(cos(θ + 3θ) + isin(θ + 3θ)) = r4(cos ...
