Homework Help: Find limit

  1. Aug 4, 2010 #1
    1. The problem statement, all variables and given/known data

    lim x->5+

    3x/(5-x)


    2. Relevant equations



    3. The attempt at a solution
    Is this a straight forward solution,
    -infinity?
    Because 3*5=15, and if x approaches 5 from the positive side, it means that (5-x)=-0.000000000001
    So, 15/-000000000000.1 = -infinity

    yep, that's right. I don't know why the somebody chose to make such a trivial example into a problem, but whatever.

    I expected to have some tricks in this problem...
