Hi! please someone help me in evaluating the integral containing branch point singularity.

\int^0_{-\acos(1/n)}\frac{e^{i\cos{z+k}}}{Sqrt{1-n^2\cos^2{z}}}dz

## Re: singularity removal

Dear Friend

Can you send me your problem completely ?

It seems that you are discussing a complex integral with a singularity at b=-acos(1/n) . If this is the case , then you need to determine a curve passing from 0 to -acos(1/n) to can define ( and compute ) it .
