## Homework Statement

"Find the radius of convergence and interval of convergence of the series"

[tex]\sum_{n=0}^\infty \frac{x^n}{n!}[/tex]

## Homework Equations

Ratio Test

## The Attempt at a Solution

[tex]\lim{\substack{n\rightarrow \infty}} |x/n+1|[/tex]

(I can't seem to get the |x/n+1| to move up where it should be)

Here's what I don't understand. What do I do if I have an N left over when I get this far?
