Phasor Problem

  1. Sep 7, 2005 #1
    Hi i am trying to solve this problem and i am stuck at finding all possible solutions, can someone please help?

    Problem: Solve the following equation for M and P. Obtain all possible answers. Use the phasor method, and provide a geometrica diagram to explain the answers.

    5*cos(Wo*t)=M*cos(Wo*t-(pi/6))+5*cos(Wo*t+p)
    hint: Describe the figure in the z-plane given by the set {z:z=5*exp(j*p)-5 where 0<(or equal) p <(or equal) 2pi

    when i converted to phasor form and solve for M, I got M=0, not sure what that means.....

    Well, if you insert M=0 in the original equation, you can immediately see what p would be.
