Here is my question: Let be analytic and suppose that . If , find .

My proof so far follows:

By differentiating with respect to x and y, we see that , , , and . In order to move back to v, I will integrate on and as follows:

To solve for c, and , so

and now this is the really dumb part... I am not sure if I am supposed to substitute this literally as u + i*v, using the u as given and the v that I have derived, substituting (0,1) for i, or do something else entirely. I feel that I am nearly at the solution, but I am losing it here in something that should be quite simple. I will appreciate your help. Thanks.
