a \sin x+b \cos (x+\theta)+b \cos (x-\theta)=d

, then the minimum value of

|\cos \theta|

View answer and explanation

Correct option: A

\frac{1}{2|b|} \sqrt{d^2-a^2}

Option A (

\frac{1}{2|b|} \sqrt{d^2-a^2}

) is correct because it represents the minimum value of |cos θ| derived from the given equation.
