Some work is needed...

The hint is probably not enough. Should really explain continuity. The other hint should be something to do with this mysterious limit you get.

The solution honestly is a mix of 3 solutions and none of them done particularly well.

L'Hopital's rule should be in solution 2.

There should be no mention of the squeeze theorem - this argument is not obvious (and if this limit is covered in class, it is covered with the squeeze theorem already) and this should not be a solution.

The first solution should be using the definition of a derivative to evaluate this limit (which of course is proved using the squeeze theorem...).

Do we feel that the continuity argument is worded well?
