Polar Representation of Sinusoidal Functions

[StrongForce]

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 $$e^{-i\,x}$$ is 1, so it represents a unit circle with center $$(0,0)$$.

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