Maybe he meant .

Here's a method. I hope it will suffice. Kind of one sided though. Let Then you get: You can always try the "ol' Hospital" rule.
L'Hôpital's rule seems to be a dead end for this problem. The second form ends up as . I don't know if there is any analytical way to solve this without the use of a substitution.
