"The formula is important because it connects complex numbers (i stands for the imaginary unit) and trigonometry. The expression "cos x + i sin x" is sometimes abbreviated to "cis x"."

I just find out the website which you can check out.
Hope it will help you.

You have to read it because it just doesn't work as text.

This was the best explanation I could find. The other ones I couldn't begin to understand.
