Determine if the series is convergent or divergent

vendredi 1 août 2014

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

[itex]1+\dfrac{2^2}{2!}+\dfrac{3^2}{3!}....... \infty[/itex]





3. The attempt at a solution



[itex]t_n = \dfrac{n^2}{n!} \\ \dfrac{n}{(n-1)(n-2).....1}[/itex]



I tried applying the Ratio Test but couldn't find another function which would give me a finite limit when divided by that function.
