    Hey guys :)

    Hey guys, i'm doing a lab report and I'm having some trouble understanding the following equations.

    my measurements:

    I'm having some real problems trying to just use the equation.

    What I have so far
    az = [tan^(-1)](R/x)
    given R = 2.68
    L = 49.3
    X = 2∏fL = 15.5

    I just don't know how to work the complex numbers in the equation...:confused:
    Let me know if you need more background

    thanks guys

    so I can get it down to-

    (25.429<-80.19)sin(delta + 9.81) + 4.33<-160.38

    But I don't know what to do with multiplying the complex number with SIN.

    also I don't know if I did this bart correctly-
    [V2^(-2)] / (Z^(2))
    = 1072/[(15.73<80.19)(15.73<80.19)]
    = 4.33<-160.38

    What do you guys think?
