Hi guys

I've been doing some practice problems on integration and this particular one stumped me.

Int(|sqrt(x)-1|.dx)

Evaluate the integral at (0,4).

So far I've gotten this when x>1, sqrt(x)-1>0, so the integral is 2/3.x^(3/2)-x+C. I'm still stuck on the (0,1) portion.

I'm a little rusty at integration so any advice would be appreciated.

Thanks.
