De Moivre's formula
Here, is Euler's number, and is often called the polar form of the complex number .
The formula is very important because it connects complex numbers and trigonometry. It can be proved using the trigonometry form of complex numbers by mathematical induction, with the help of some trigonometrical identities. It can also be proved using Euler's formula as well. 
By using this formula, any equation of the form , where w is complex, can be solved.
