It will be fine if the forum can support latex formula ?!
I'm sure that you agree... but just hope that you will find some time to add it

Thanks for your community

We can derive de Moivre's formula using Euler's formula:
\[
\left( \cos{\theta} + i \sin{\theta} \right)^n = \left( e^{i\theta} \right)^n = e^{i (n \theta)} = \cos{(n \theta)} + i \sin{(n \theta)}
\]

EDIT: Seems to work. Will this do for now?
