08 - The Exponential Form (Euler Form)

The Polar Form is a very useful form for representing a complex number.
Our vector that represents this complex number may be treated as a pointed arrow as we remember, and we can assemble this in terms of trigonometric functions, where we have
The is the of this complex number, a scaling factor for a pointed arrow, while the expression is the arrow itself, where the is the angle it points in, meaning the of the complex number, where these are calculated as
