Let

S

be the set of all

\alpha \in R

such that the equation,

\cos 2x + \alpha \sin x = 2\alpha - 7

has a solution. Then,

S

is equal to

View answer and explanation

Correct option: D

[2, 6]

Option D ([2, 6]) is correct because it represents the range of values for

\alpha

for which the given equation has a solution, derived by analyzing the range of the sine function.
