1. The problem statement, all variables and given/known data (integrate: upper limit 3; lower limit 1)(dx/((x^(1/2))(x+1)) 2. Relevant equations 3. The attempt at a solution First of all, somebody needs to show me how to get the actual integration sign to show up on the forums. Anyway, I was pretty confused with this one. I tried making u be x+1 and du=dx, but I was afraid this wouldn't solve for the radical x that I also had. Than I tried making u be x and du be dx, but then that wouldn't solve for the x+1 that I had. I don't think I can break this up into two different equations, so I'd like some help.
