I need to integrate 1/sqrt(u^2)

Now i can't just apply the square root because then i lose all information about the minus values. I've tried various substitutions, trig ones seem to make it worse and I've run the integral in mathematica and it returns an answer that i agree with and fits with what I am trying to do but I am not sure how to get it :S

Im sure its something simple that my tired caffeine saturated brain is missing, so be gentle with me :P

Cheers
