Rectangular vs. Polar Form—An Engineering Point of View

To work with complex numbers, it helps to have a standard mathematical notation. There are two basic forms of complex number notation:

· Polar form

· Rectangular form

Polar form is where a complex number is denoted by the length (also known as the magnitude) and the angle. In rectangular form, the complex number is denoted by its respective horizontal and vertical components.
