The answer is undefined.

Explanation:

Some people might say that the answer is 25/24, and technically, they aren't wrong, because:

f(f^-1(x))=x

and in this case:

sin(sin^-1(25/24))=25/24

But this actually isn't true. If you try to simplify the problem, you'll find that the domain of sin^-1x is [-1, 1], and 25/24 is outside of that (basically, sin^-1 literally can't take in numbers bigger than 1 or smaller than -1).

Therefore, it cannot be simplified further.
