Homework Statement



What would the geometric explanation of exp(-i*x) be?

Homework Equations



Exp(-i*x), i being (-1)^1/2

The Attempt at a Solution



I'm pretty sure this is just a circle, created clockwise? Just want to check.

The magnitude of [tex]e^{-i\,x}[/tex] is 1, so it represents a unit circle with center [tex](0,0)[/tex].

If x varies on [tex][0,2\,pi)[/tex] the circle is created clockwise.
