The cancellation property sin−1(sin(x)) = x is valid for x in what interval
pochemuha

Answer:

It is given that : Sin^{-1}(Sin (x) =x

As we have to find the Domain of Sin^{-1}(Sin (x).

-1 ≤ sin x ≤1

Sin^{-1}(-1)\leq Sin^{-1}(Sin x)\leq Sin^{-1}(1)\\\frac{-\pi}{2}\leq x\leq \frac{\pi }{2}

So it is defined for x lying between (\frac{-\pi}{2}, \frac{\pi }{2}) .

As meaning of Domain is those values of x for which any function f(x) is defined.
