x-> infinity

Any help on how to go about doing this would be fantastic.

Thank You.

I've glanced at this literally as I'm about to go to bed so I might be on the wrong track .... it looks like you might use the MVT to establish some inequalities that can be used to set up a squeeze/pinching/sandwich thereom situation ....

bump... any ideas???
