Finding the Roots of a Complex Number - Concept

Concept Concept (1)

We can use DeMoivre's Theorem to calculate complex number roots. In many cases, these methods for calculating complex number roots can be useful, but for higher powers we should know the general four-step guide for calculating complex number roots. In order to use DeMoivre's Theorem to find complex number roots we should have an understanding of the trigonometric form of complex numbers.
