Homework Help: Solve the limit

  1. Sep 11, 2012 #1
    1. The problem statement, all variables and given/known data

    Solve the limit: lim n→∞ (√(n^2+1) - n)

    2. Relevant equations



    3. The attempt at a solution

    I am very lost on how to start so I do not have anything

    Multiplying by 1 in the form of (sqrt(n^2+1)+n)/(sqrt(n^2+1)+n) is probably the easiest way to go. There's other ways to do it. Try that one first.

    Have you tried multiplying by the conjugate?

    edit: too slow.
