Homework Statement


Evaluate the limit analytically if necessary using L’Hopital’s rule:
lim x->0 (1+x)1/x


Homework Equations





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.
