I am considering the integral of $z^{s-1}e^{iz}$ (where $0
I used the usual approximation of the modulus of the integral by the maximum modulus of the integrand on the path times the length of the path but it wasn't giving me an upper bound that was approaching 0. I am wondering what other method I should be using or whether the integral does approach 0?
