I have to use l'hopital's rule to find each limit:

1. lim x approaching 0 from the right of

(1-cos(sqrt x))/x

Since this is a 0/0 form I use l'hopitals rule. making it:

Lim x approaching 0 from the right of (sin(sqrt x))/(2 sqrt x).

Again this is a 0/0 form but if I just keep applying l'hopital's rule it always comes up with a 0/0 form. How do I solve this?
