Homework Help: Limit of a trigonometric function without l'hopitals rule?

  1. Apr 26, 2012 #1
    1. The problem statement, all variables and given/known data

    lim of (sin(x)/(x+sin(x)) as x approaches 0

    2. Relevant equations

    3. The attempt at a solution
    I tried using trigonometric identites to figure it out but I can't do it, and when I looked up help for it I only found solutions that utilize the l'hopitals rule. I have to know how to do these questions without this rule, can someone at least get me started in the right direction please? Thanks.

    Try dividing the top and bottom by x.
