hmmm $$\bf sin^{-1}(sin(\theta))\implies \theta$$

2. anonymous

as far as the range, yes, that's the default range constraints for the inverse sine

3. anonymous

but I don't think we can get an absolute angle value from that

$$\bf y = sin(x)\implies sin^{-1}(y)=sin^{-1}(sin(x)\implies sin^{-1}(y)=x$$
