Phasor conversion help

  1. Jan 24, 2006 #1
    I can convert sinusoids to phasors and vice versa if they are relatively simple, but I don't know how to deal with these two.


    I was going to distribute, and make two vectors and find the resultant vector, but I don't think thats how to go about it. also

    Thanks ver much for any hints or secrets.

    Where's the second one?
    Just put the first factor into polar form and multiply, like so:
    (8-j3)*5*exp(-jx) = Sqrt(73)*exp(-j*0.3588)*5*exp(-jx) = 5*Sqrt(73)*exp(-j*(x+0.3588))
    which converts to 42.72*Cos(wt - x - 0.3588), assuming, of course, that the phasors are of the same frequency, w.
