Euler's formula is the following identity in complex analysis making use of the imaginary number :

Euler's Identity

The formula can be used to derive an equation known as Euler's identity:

This is called the most beautiful equation in all of mathematics, because it equates the five most common mathematical constants in a perfectly elegant manner.
