Read below.

Explanation:

For our situation of sin1(sin1(π3)), we are asking ourselves: In our unit circle definition, what angle gives us the hight of π3?

Just note here that π31.0471975511965976

The maximum height a point on the unit circle can maintain is 1. (Similarly, the minimum is 1).

No angle value can give you a value less than 1.

Therefore, no angle satisfies our requirement.
