Proof of Limit

  1. Jun 26, 2016 #1
    1. The problem statement, all variables and given/known data
    I have been working on the problem below and I am stuck. I am stuck primarily because of the part where is says x=0. If x-0, it should cancel everything out. The derivative of 0 is 0 so will cancel everything out I think, so I am not sure if that is the reasoning and the proof behind it.

    2. Relevant equations


    3. The attempt at a solution
    I thought I should start this way, but I am not 100% sure.

    It's a good idea to have the problem statement visible in the OP.

    L'Hopital's rule?

    Not necessary with the hint in the OP, the definition of a derivative is enough.
