Web15 mrt. 2024 · Now, we have to find the minimum value of the expression ( 3 cos x + 4 sin x + 5) by adding 5 to the minimum value of ( 3 cos x + 4 sin x). So, we get the minimum value of the expression ( 3 cos x + 4 sin x + 5) as − 5 + 5 = 0. Hence, the minimum value of ( 3 cos x + 4 sin x + 5) is zero. So, option (D) is the correct answer.
