I need help with this integral
integral of arctan of the square root of (1-x) in dx
thanks for your help
It is not on my book..I made the same substitution and tried to go on by parts considering u as the derivative of u^2/2 but then I got stuck on the integral u^2/(1+u^2) in du. Can you tell me the standard integral so that the solution might help me see how I can go on? Thanks
