Howdy,

I need some help finding this limit:

$\displaystyle lim \Delta x -> 0$

$\displaystyle \sqrt{x+\Delta x}-\sqrt{x}$

______________________________

$\displaystyle \Delta x$

(P.S. Sorry I was having a bit of trouble using the \frac command, just so you know it's suppose to be delta X on the bottom of the fraction as I tried to show using the ___). Thanks.
