Complex variables: Imaginary part of the Mobius transform
If where and
Show that: where .
I think that can be written as the above statement but I am stuck on how to get the conjugate of L(z). I am a little rusty with complex variables. Thanks for your help.

But , since , so , and you're done.
BTW, the formula is pretty weird...it's true, but too fancy, imo.
