Hi, I'm having a little trouble with a substitution/integration by parts question...

find the integral of: ln(sqrt(x) +1)

the book lists the first step as substituting y = sqrt(x) +1

from there i tried integration by parts using u=lny, v'=1 but it didn't quite work out

the solution in meant to be: sqrt(x) - x/2 + (x-1)ln(1+sqrt(x))

any suggestions?

thank you!
