1. The problem statement, all variables and given/known data I have to solve the following integral 1/(sqrt[x] * ln[x]) from 2 to infinity 2. Relevant equations 3. The attempt at a solution u= ln[x] dv=1/sqrt(x) du= 1/x v= 2 sqrt(x) If I do this I get lim (ln b/ sqrt[x] - 4 sqrt[x] - ln2/sqrt[x] + 4 sqrt[x]) Is this the actual result of the integral? Did I substitute correctly? Thanks in advance!
