Homework Statement



is there a way to solve

lim (x->0) [tex]\frac{x - sinx}{x^{3}}[/tex]


using the fact that sinx / x = 1

or is it much more complicated.. i've tried to break it down into sinx/x everyway i can think of with no luck..

Do you know l'Hopitals rule?

I am thinking of a way to do it with only sin(x)/x but can't come up with a good way immediately.
