The derivative of

{\sin ^{ - 1}}\left( {\frac{{\sqrt {1 + x} + \sqrt {1 - x} }}{2}} \right)

with respect to

x

View answer and explanation

Correct option: A

- \frac{1}{{2\sqrt {1 - {x^2}} }}

Option A,

- \frac{1}{{2\sqrt {1 - {x^2}} }}

, is correct because it is the result of differentiating the given inverse trigonometric function after a suitable substitution to simplify the expression.
