hah, you got that from that sqrt(x-2)/sqrt(x-1) thing, right?

sect(tan^2t)=sect(sec^2t-1)=sec^3t-sect

\[\int\sec^3 tdt\]\[u=\sec t\]\[dv=\sec^2 t\]integrate by parts

I've gotten that far in the equation already, just not sure what to do with the sec^3 t

^there it is
this will be one of those integrals that repeats, so you will wind up adding the integral of sec^3 to both sides
you will still have to integrate sec though, hope you remember how to do that ;)
