Ʃ n/e^n converge or diverge

2. Relevant equations

3. The attempt at a solution

I got this down to an improper integral using the integral test but I am weak at L'Hospitals rules and I was wondering if someone could help me out

I have

[itex]\int n/e^n[/itex] from 1 to infinity

down to

Limit b to infinity ne^n - e^n |from 1 to b

this gives me infinity - infinity so time for L'Hospitals ( forgive my spelling)

I know to divide by the recripical of either one but I get stuck from there
