If in a triangle

A B C, 2 \cot B \cot C=1

, then

\cos B \cos C

will be equal to

View answer and explanation

Correct option: C

\cos A

Option C (

\cos A

) is correct because the given condition

2 \cot B \cot C = 1

can be manipulated using trigonometric identities to show that

\cos B \cos C = \cos A
