    so, for this problem, the range is -1 to 1?

    y is the angle.  Wouldn't it range from -inf to + inf?   (4n+1)*PI/2 for all n  ?
check my thinking.

    I still don't get it. How come y is the angle?

    The original equation, I read:
y is the angle whose sine is x
y=arcsin x
    
y is the angle whose sine is x
y=arcsin x
