1. The problem statement, all variables and given/known data I have to use the comparison test although I'm bad at coming up with what to compare it to 2. Relevant equations What if I compare it to 1/sqrt(x) 3. The attempt at a solution I take the integral of 1/sqrt(x) from [0,PI] I get -2sqrt(x) and then I use limits and evaluate I get 2sqrt(PI) Can I do this? So since this integral is larger then the one in question my integral converges?
