Polar Form nth Root of Complex Numbers where: Vz = is designated as W, k = 0, 1, 2...(n– 1) W, = principal value or root, and e must be a positive angle. W,, W,..W = auxiliary values or roots De Moivre's Theorem (Abraham de Moivre) Raise both sides to the power of n z" = (rZ0)" z" = r"Zne Exercises 2 1.
