hi im stuck on a question and dnt knw what the answer is about..

Xn=(n^4+1)/(n^4-4). for n>2.

it asks me to determine L=lim n->infinity Xn

for each positive real number e, determine an integer No such that |Xn-L|<e for all integers n>No

is it because 1/n^4 converges to 0 that the L=1. what do u do with this limit?

nope.. my lecture notes arent very informant.. sorry bout that.

the answers are quite confusing. because they get 1+5/(n^4+1). dnt knw where that 5 came from? - May 3rd 2008, 03:37 PMPlato
