Homework Help: Plotting Phasor representations of functions

  1. Jan 15, 2008 #1
    1. The problem statement, all variables and given/known data

    Plot the following for x = 0 to 8:

    This is part of a larger engineering problem, but I am stuck here, I have no idea how to plot a phasor.

    The original function is:


    2. Relevant equations

    3. The attempt at a solution

    And the phasor representation...


    How do I plot that?!?!?!?

    The plot will be a circle in the complex plane of radius 2. The phasors will be points on the circle with angle given by [itex] - \frac{\pi}{4} x[/itex].
