3 \sin \theta+4 \cos \theta=5

, then the value of

3 \cos \theta-4 \sin \theta

is equal to

View answer and explanation

Correct option: A

0

Option A (0) is correct because by squaring both sides of the given equation and using trigonometric identities, we find that

(3 \cos \theta - 4 \sin \theta)^2 = 0
