find an analytic function F where F' = f(adsbygoogle = window.adsbygoogle || []).push({});

f(z) = z-2

f(z) = ((z^4) +1)/(z^2)

f(z) = sinzcosz

I know I have to put these into the cauchy riemann equations but I dont know what to use for my du/dx or du/dy because im not sure to use x-2 for my du/dx etc or if im supposed to integrate first. I dont know which parts of the equations fit into the riemann-cauchy equations. My book only gives one example and I dont know how to relate these, please help
