The question asks: Find G'(x) when G(x)= .

Apparently the solution is G'(x)=((arcsin(x))/(2+x))/x , but this doesn't seem right to me. I thought you would replace (2+x) with (2+sin(x)). Can someone please clarify? Thanks

(edit: sorry the limits of the integral are between ln(x) (upper) and a. I can't seem to change it.)

For anyone who wants to help.

Also I think you can just plug the limits into by application of the FTC although that may well be wrong.
