The Euler Formula - Concept

Concept Concept (1)

One formula that is used frequently to rewrite a complex number is the Euler Formula. The Euler Formula can be used to convert a complex number from exponential form to rectangular form and back. The Euler Formula is closely tied to DeMoivre's Theorem, and can be used in many proofs and derivations such as the double angle identity in trigonometry.
