Complex Numbers and Its Different Forms
Complex Numbers can be written in three forms or notations:
1. Rectangular
2. Trigonometric
3. Polar
For example, the following vector can be described using three different forms:
Rectangular Complex Numbers
Rectangular Complex Numbers are denoted by its horizontal and vertical components.
Example: $ X = 0.5 + \frac{\sqrt[]{3}}{2} j $
Trigonometric Complex Numbers
Complex Numbers can also be expressed in trigonometric form.
Example: $ X = cos60^{\circ} + jsin60^{\circ} $
Polar Complex Numbers
Polar form is when a complex number is described by its length and angle.
Example: $ X = 1 < 60^{\circ} $
