What if n is a negative integer , would it be

[tex]\sin^{-1}b=(\sin b)^{-1}=\frac{1}{\sin b}[/tex]

I dont think this is right , because properties of indices only works for numbers and NOT function , but why it works for case 1 above ?

What if it's [tex]sin^{-3}b[/tex]

How bout if n is rational ?
