I can't do this one :-(
Prove from the definition that -> 1 as n ->
My lecturer wrote on the board that we should be answering the question as follows (he never gave us an example though!):
For a given positive h you must ensure that the difference of and 1 can be made to stay less than h. When you have an expression for the difference, look for a related simpler expression that can easily be made less than h.
Haven't got a clue, please help.
