    Help with evaluating limits of exponents and logs

    Could someone help with evaluating limits of e and ln. The manual I have does a pitiful job explaining this.

    For example, the question is

    evaluate

    lim ln (x-2)
    x->2+

    Thanks!

    let y = x - 2, then as x \to 2^+ we have y \to 0^+. and so your limit becomes

    \lim_{y \to 0^+} \ln y

    which you should know. think of what the graph of the natural log looks like
