Number 6 on pretest

The domain of sin -1 (ln x) is________________?
Does anyone have any suggestions? I know the domain of sin^-1 (x) is the range of sin(x) which is [-1.1]. However, how does the ln(x) fit in?

This means that the range of ln(x) would have to be [-1,1] because the range of ln(x) would be the domain of sin^-1(x). So the domain of the entire function would have to be [1/e,e].
