I forgot to include one thing...these questions followed on from a question proving that provided that f is an invertible function. By the way we are instructed not to use that rule as it is not in the syllabus...

By the way we are instructed not to use that rule as it is not in the syllabus... ok, now we're getting somewhere. note that the inverse of is so the first limit is equal to , and the rest is easy now for the second one: what's the inverse of ?
I finally got it now! I get the inverse as and it follows from there that the limit I need to find is equivalent to , and that answer is confirmed by my calculator
