# 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 $$h$$.
