Homework Help: Real Variables In Complex Equation

  1. Sep 20, 2011 #1
    1. The problem statement, all variables and given/known data
    The problem asks to put the following expressions in z={ReA(e^i*)(e^i*)} Form





    2. Relevant equations

    3. The attempt at a solution

    The problem is I don't even know which parts are real and imaginary because there is no i value in any of them. I used eulers equation and expand them but arrived at a equation with only one i, two cos, and a sin. Is this the right approach or am I missing the point.

    Ya That does help a lot does this mean for


    The Real Part would be

    Re{e^i(wt-pi/2) + 2e^i(wt-pi/3) - e^i(wt)}

    in complex phasor amplitude
