Hello,

I was wondering if someone could help me solve the integral of the following:

int(sec^2(sqrt(x))dx).

Now, I tried letting u = sqrt(x), but that gets me nowhere; I wouldn't be able to integrate by parts, as what would I let dv be? Trying to let u = the whole function does little good...maybe I am missing something (well, obviously I am!).

Ugh.

Thanks in advance for your help!!
