Hi all, I'm new here, and just have a quick question:

Evalute: lim as x[tex]\rightarrow[/tex][tex]\infty[/tex] of [tex]\frac{x - sin x}{x^{3}}[/tex]

2. Relevant equations

l'hopital's rule?

3. The attempt at a solution

So far I've used L'hopital's rule to get it down to lim as x[tex]\rightarrow[/tex][tex]\infty[/tex] of [tex]\frac{cos x}{6}[/tex]

but after that, I don't know what to do... I'm pretty sure that I have to use an extention of L'hopital's rule

thanks!
