Let

S

be solution set for values of

x

satisfying

\cos ^{-1}(2 x)+\cos ^{-1} \sqrt{1-x^2}=\pi

, then

\sum\limits_{{x \in S}} 2 \sin ^{-1}\left(x^2-1\right)

is equal to:

View answer and explanation

Correct option: B

-\sin ^{-1}\left(\frac{24}{25}\right)

Option B (

-\sin ^{-1}\left(\frac{24}{25}\right)

) is correct because solving the equation for

x

and substituting it back into the expression yields

-\sin ^{-1}\left(\frac{24}{25}\right)
