Hey guys.

I have this question, I took it from a test.

I need to check if there is an analytic function F(z) in this area (in the pic) that has this derivative (in the pic).

Well, the derivative is analytic in this area, right?

If the derivative is analytic, shouldn't F(z) be analytic and even more important, can it be that easy ?

I'm not sure about the answer, I could really use some help.

Thanks a lot.
