^{ln(sin(x))}f:R-->R.

Can we write this function defination like this f(x)=x f:R-->R

I think no because if we put x as any negative number in first function(function in first line) then there will no solution exist for this but if we put x as any negative number in second function then their will be a solution.

So does it mean that e

^{ln(x)}=x Is not true always.

ln represent natural log wih base e. R represent set of all real numbers.
