Impossible Integral!

[sjud9227]

I'm trying to find an integral using an integration table but for the life of me I cannot figure it out.

It's the integral of:

(sec^2x) / (tan^2x)*sqrt(tanx-1) dx

I was thinking I could let u=tanx and du=sec^2x and then I could try and find one on the table that way but I can't find one to match that. If anyone has any suggestions or even how I can solve this I'd appreciate it!

Wolfram Alpha can't even solve it! lol

Thanks for any help!

In table "forms involving (a+ b*u)^0.5", a reduction formula (a+b*u)^0.5/u^n maybe helpful
