Integral involving the gamma function

192 Views Asked by At

If we define $$f(x) = 1 + \frac{\cos\big(\pi\frac{\Gamma(x) + 1}{x}\big)}{2 - \cos(2\pi{x})}$$ how would one go about evaluating $$ \int_1^R \frac{1}{x} \log{f(xe^{i\alpha})} dx$$ for some parameter angle $\alpha$ and an arbitrarily large $R$ (needs to hold above any particular constant threshold)? I know I'm supposed to show some progress but I really have no idea how to do this.
