1. The problem statement, all variables and given/known data Find U(x,y) and V(x,y) for f(z) = -(1-z)/(1+z) Find Ux, Vy, Vx, Uy (partial derivatives) 2. Relevant equations z = (x+iy) 3. The attempt at a solution I found U(x,y) and V(x,y), and I used the quotient rule to find the partial derivatives Ux, Vy. They should be equal given the C-R relation, but they are off by a factor of x in Vx. I am attaching my work, I have checked the algebra and am not seeing an error, maybe someone else has insight into my problem? Should I be using polar form to figure this out? I've been killing myself on this one today, any help is appreciated.
