Actually I have given the answer to question b) with this quote:
sin(arcsin x ) = x if x belongs to interval [-1,1] right?
because i wrote in interval [-pi/2, pi/2].
Yes that's correct! Sorry, I hadn't seen that. Because the range of is the closed interval [-1,1] that means the domain of (the inverse function) is indeed the interval [-1,1].
