I'm not sure of how to differentiate z z-conjugate. I used and and started to differentiate to get . When I get to it's very bloated. Is there a neater way of doing this than my way?
To check whether u is harmonic or not I need to check if

Functions involving conjugates are generally not analytic. That means you may just have to do this by brute force (as you've been attempting). I don't see any clever tricks off the top of my head. I'm curious if anyone else comes up with anything quick.
