\cos x=\frac{2 \cos y-1}{2-\cos y}

, where

x, y \in(0, \pi)

, then

\tan \frac{x}{2} \cot \frac{y}{2}

is equal to

View answer and explanation

Correct option: B

\sqrt{3}

Option B (

\sqrt{3}

) is correct because by substituting the given expression for

\cos x

into the half-angle formula, we can simplify and find the value of

\tan \frac{x}{2} \cot \frac{y}{2}
