Hi everyone. I'm a bit stuck on doing this Delta Epsilon prrof for the limit

lim x->1 $\displaystyle \sqrt{x}$=1

I have (I'll use brakets for absolute values)

( $\displaystyle \sqrt{x}$-1)<e and 0<(x-1)<d

so

(x-1)<$\displaystyle e^s$

so d=$\displaystyle e^2$ ?????

ok then i'm stuck and don't know where from here...i'm not even sure if i have done that right

any help?
