so: I know you're supposed to take the limit of the integrals, but I'm having trouble getting started. Without the limits, I found the indefinite integral to be 12arctan(sqrt(x)) +C

well it converges, but you don't need to split it into two integrals, just put

the substitution? just apply it, can you show what do you get?
just subbing it in would just give would it not?
no it's wrong, try again, the integrand has de arctangent form.
so the integral would be which is equal to right? but after finding the integral, what do you do next to find the definite value from 0 to infinity?
