Homework Help: Cacl 2 Integration

  1. Nov 15, 2007 #1
    1. The problem statement, all variables and given/known data

    Integral of sqrt(x-1)/sqrt(x)

    2. Relevant equations

    3. The attempt at a solution

    I think I have to sub x = sinh2 so you get sqrt(1-sinh2)/sqrt(sinh2)
    I forget what to do after this

    I'm not totally sure that [tex] x = \sinh^2(u)[/tex] will help you in this case since then [tex] x-1 = cosh^2(x)-2[/tex]. Trying [tex] x= cosh^2(u) [/tex] should lead to better results.
