Hi, no actually just assuming that the function is differentiable, I just wanted help to derive the partial differential equations (du/dx, du/dy, dv/dx and dv/dy).
Hi,
I am currently teaching myself complex analysis (using Stein and Shakarchi) and wondered if someone can guide me with this:
Find all the complex numbers z∈ C such that f(z)=z cos (z ̅).
[z ̅ is z-bar, the complex conjugate).
Thanks!
