Find the limit:
the answer is so i guess we should get something like .. but dont know what to do with double n and exp. also:
so thats but again, what to do with exp?
This one is a particular case of the question in this thread.
First of all, start by writing the sequence as . Then, use asymptotic expansions in the exponent. Note that , which evokes a Riemann sum; thus we can avoid Stirling's approximation.lso:
