I was reading several articles on Euler's identity, which is:
e^(i*x) = cos x + i*sin x
I understand what this formula describes: the unit circle on the complex plane, but I never really understood why e is there from a geometric point of view. So my question would be, what relationship does e have with the unit circle and why is it, as a result, a part of the formula?
Any links would also be greatly appreciated.
