1. The problem statement, all variables and given/known data Going over past exam problems, stuck on this one. Attached Calc 2, topics include for this exam integration techniques, such as partial fractions, improper integrals, trig sub, and series. Question reads: Use a substitution to compute: (see attached) 2. Relevant equations 3. The attempt at a solution I tried partial fractions integration. 1. dx/x(1 + sqrt(x) 2. A/x + B/(1+sqrt(x) = 1/x(1+sqrt(x)) Solved for A, A= 1 B = -1 Resulted in: 1/x - 1/1+sqrt(x) I integrated each part: ln(abs(x)) - (ln(abs(1+sqrt(x)))*(1/2sqrt(x)) I am not sure if this was correct.
