Separating complex numbers

  1. Nov 18, 2007 #1
    1. The problem statement, all variables and given/known data
    U-i*V=ln((z-1)/(z+1)) - solve for U and V, where U is the real part and V is the imaginary part, of this equation

    2. Relevant equations
    z=x+i*y, where x and y are the real and imaginary parts respectively

    3. The attempt at a solution
    I've attempted raising it to the power e, but that didn't help, I also tried z=r*exp(i*theta) but that didn't seem too help much. I'm really stuck on this one. Thanks.

    First write (z+1)/(z-1) in the form A+Bi where A and B are real. Then convert that to the polar form.
