How one can find the real and the imaginary parts of $f$

by China   Last Updated August 14, 2019 09:20 AM - source

Let us consider the function:

$$f(s)=1/(iπ)*(log(h(s)/g(s)))$$

where $h$ and $g$ are complex functions such that the $log$ function is well defined and $i²=-1$.

My question is: How one can find the real and the imaginary parts of $f$ in term of the the real and the imaginary parts of $g$ and $h$.
