Do you mean to ask  Is the output from the inverse sine function a Real number in the interval [-pi/2, pi/2] ?
 
If so, the answer is YES.

P.S. The input to inverse sine function (i.e., the argument, is always a number in the interval [-1,1], i.e. some "sine value").  That's the domain; the output (in radians) is the range of the inverse sine function.
