One sided limit

  1. Apr 20, 2010 #1
    1. The problem statement, all variables and given/known data

    Calculate the one-sided limit as x->-1+

    2. Relevant equations

    lim
    x->-1+ |x2-1|/x2-1

    3. The attempt at a solution

    Here x > -1 since it is approaching -1 from the right side.

    therefore + (x+1)(x-1)/(x+1)(x-1) = Negative/Negative

    so my final answer is +1.

    Is it correct??

    Thanks!!

    But I couldn't get that :uhh:

    Since it is an absolute value and x is approaching from right then x>-1. Then how that (-) sign comes.????
