1. ## Tough limit

I'm having trouble finding a limit and would appreciate if someone could point me in the right direction.

I'm looking for the

lim arcsin(1-sqrtx)/(1-x)
x->1

The equation looks like this

- Wolfram|Alpha

In its current form is undefined. What can I do?

I'd use L'Hopital's rule.
