Limit of a Sequence

mercredi 31 juillet 2013

1. The problem statement, all variables and given/known data

Find the limit of n22n/(n!)





2. Relevant equations







3. The attempt at a solution



First I expand out 2n/(n!) = (2/1)(2/2)(2/3)(2/4)...(2/n) which gets increasingly small as n increases. Now, where does the n2 fit into this? I know the limit to be 0 but I can't get passed this point. Any pointers?
