The domain of the function f(x) =sqrt(sin^(-1)x) is:

[0,1]

`[-1,1]`

`(-infty, infty)`

`(0,1)`

`((2n-1)pi, 2npi)`

`(2npi, (2n+1)pi)`

`(2npi, 2npi + pi/2)`

`phi`

`[ 2 n pi - pi/3, 2 n pi + pi/3]`

`[ 2 n pi - pi/6, 2 n pi + pi/6]`

`[ 2n pi - pi/2, 2 n pi + pi/2]`

`[2 n pi - pi/3, 2 n pi + pi/2]`
