The most general values of θ\theta satisfying the equation (1+2sin⁡θ)2+(3tan⁡θ−1)2=0(1+2 \sin \theta)^2+(\sqrt{3} \tan \theta-1)^2=0 is/are given by
View answer and explanation
Correct option: C
2nπ+7π62 n \pi+\frac{7 \pi}{6}
Option C (6) is correct because solving the equation tan⁡x+cot⁡x=2csc⁡x\tan x + \cot x = 2 \csc x leads to cos⁡x=12\cos x = \frac{1}{2}, which has 6 solutions in the interval [−2π,2π][-2\pi, 2\pi].
