Do I even need to use L'Hopital's Rule for this

  1. Mar 29, 2010 #1
    1. The problem statement, all variables and given/known data
    Evaluate the limit analytically if necessary using L’Hopital’s rule:
    lim x->0 (1+x)1/x


    2. Relevant equations



    3. The attempt at a solution
    Well, I can get the thing equal to 1 if I just plug in zero, so do I need to use L'hopital's? This whole thing is very confusing...

    How can you 'plug in 0'?? 1/0 is undefined. Besides the limit isn't 1. I suggest you use l'Hopital.

    To be honest, it's late and I've been doing this stuff for 9 hours straight. It didn't even cross my mind that 1/0 would be undefined.

    Gotcha. So just take the log and use l'Hopital on the result.
