Polar Form

A Complex Number z can be specified by using Polar Coordinates. The representation of a complex number by its polar coordinates is called the Polar Form of the complex number.

Polar Form Notation

Trigonometric Form of Polar Form Notation:

$ z = r\,(\cos \varphi + i\sin \varphi )\, $

Exponential Form of Polar Form Notation:

$ z = r\,\mathrm{e}^{i \varphi}\, $
