L'Hopital's Rule is a theorem dealing with limits that is very important to calculus.
Theorem
The theorem states that for real functions 
, if 
![\[\lim\frac{f(x)}{g(x)}=\lim\frac{f'(x)}{g'(x)}\]](http://latex.artofproblemsolving.com/6/7/6/67664051ac365e271260749b981666330b2b71af.png)
Note that this implies that ![\[\lim\frac{f(x)}{g(x)}=\lim\frac{f^{(n)}(x)}{g^{(n)}(x)}=\lim\frac{f^{(-n)}(x)}{g^{(-n)}(x)}\]](http://latex.artofproblemsolving.com/f/6/6/f66ad9bb5b49e51afc1bf4dac34285dae981fd6f.png)
