WebThe correct option is B sin 2 θ + cos 2 β Explanation for the correct option. Given that, sin - 1 ( x) = θ + β and sin - 1 ( y) = θ - β. ⇒ x = sin ( θ + β) and y = sin ( θ - β) 1 + x y = 1 + sin ( θ + β) sin ( θ - β) 1 + x y = 1 + sin 2 θ - sin 2 β Using the identity, sin 2 A + cos 2 A = 1. 1 + x y = sin 2 θ + cos 2 β Hence, option B is correct.
