Very basic limit

  1. Apr 9, 2010 #1
    I'm sorry for being pathetic but I can't seem to solve anything this days.

    [tex]lim sqrt(x^2-9)/abs(3-x) as x->3+[/tex]

    Hi gipc! :smile:

    You mean limx->3+ √(x2 - 9) / |3 - x| ?

    Well x -> 3+ means you only have to consider x > 3, so |3 - x| = x - 3 …

    does that help? :smile:
