Mark the Correct alternative in the following:

The general value of x satisfying the equation is given by

A.

B.

C.

D.

Answer :

Cos2x=(√3-√3sin x)2


1-sin2x = 3+3sin2x-6sin x


4sin2x-6sin x+2=0


2sin2x-3sin x+1=0


sin x = 1 or 0.5


We know,


x = nπ + (-1)nθ



Therefore, the values of x are



So, these values are obtained for different value of n from the equation



So, Option B
