NEVERMIND! IT IS 0! I SOMEHOW WAS STARING AT THE WRONG ANSWER SHEET FOR A LITTLE BIT! THANK YOU!
1. Homework Statement
Determinte whether the sequence converges or diverges:
(n^2)/(e^n)2. Homework Equations
The book says that the solution is: e/(e-1).
However, the limit of the equation y=(n^2)/(e^n) as n goes to infinity is 0.
I don't know why I can't seem to apply the theorem that:
If the limit as x goes to infinity of f(x) = L and f(n)= an, then the limit of an as x approaches infinity is L.
3. The Attempt at a Solution
I used L'Hôpital's rule to prove the limit is 0. Wolfram alpha confirms this.
