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!
