WebJan 2, 2024 · We can continue this pattern to see that. z4 = zz3 = (r)(r3)(cos(θ + 3θ) + isin(θ + 3θ)) = r4(cos(4θ) + isin(4θ)) The equations for z2, z3, and z4 establish a pattern that is … WebTo find the nth root of a complex number in polar form, we use the n th n th Root Theorem or De Moivre’s Theorem and raise the complex number to a power with a rational exponent. There are several ways to represent a formula for finding n th n th roots of complex numbers in polar form. WebThe de Moivre formula (without a radius) is: (cos θ + i sin θ) n = cos n θ + i sin n θ And including a radius r we get: [ r (cos θ + i sin θ) ] n = r n (cos n θ + i sin n θ) The key points are that: the magnitude becomes rn the angle becomes nθ And it looks super neat in "cis" notation: (r cis ) = r cis n Let us use it!
