sin-1x ≥0
Now x=[-1,1] for inverse function
now range of sin-1x is [-∩/2,∩/2]
So sin-1x≥0 when x = [0,1]

The solution given by eureka123 is correct as far as principle domain is concerned....
But in general,
the solution is 2n(pi)≤x≤(2n+1)(pi) ; n=integer
This can be arrived at by seeing the values of sinx about the four quardrants

You guys really need to brush up your fundas.
Please check up what are the domains and ranges of the inverse trigonometric functions.
