Homework Statement
. I want to prove that there is one solution for e^z-z in every shifted copy of the fundamental strip by applying the argument principle to the boundary of a rectangle −M≤Rez≤M , 2kπi≤Imz≤2(k+1)πi for large M and integer k . I need help in using the argument principle here.
Homework Equations
Argument principle.
The Attempt at a Solution
I tried to compute the integral of the logarithmic derivative along the boundary of the square,but I'm stuck with it.
