\frac{1}{2} \sin ^{-1}\left[\frac{3 \sin 2 \theta}{5+4 \cos 2 \theta}\right]=\tan ^{-1} x

, then

x=

View answer and explanation

Correct option: C

(1 / 3) \tan \theta

Option C ((1/3)tan(theta)) is correct because, by simplifying the expression inside the inverse sine function and using trigonometric substitutions, we find that x = (1/3)tan(theta).
