If a = arc sin(2), sin a = 2. But sine value cannot exceed 1. So, the given expression is invalid.

Let a = arc sin (2). Then. sin a = 2.
Strictly, $| sin a | \leq 1$ $|sin a| <=1$ . Here in the second term, sin a = 2 > 1..

What does 2sin(arccot(4))−3sin(arcsin(2))2sin(arc cot(4))-3sin(arc sin(2)) equal?
