If α,β,γ\alpha, \beta, \gamma are the angles which a half ray makes with the positive directions of the axes, then sin⁡2α+sin⁡2β+sin⁡2γ\sin ^2 \alpha+\sin ^2 \beta+\sin ^2 \gamma is equal to
View answer and explanation
Correct option: B
2
Option B (2) is correct because sin⁡2α+sin⁡2β+sin⁡2γ=2\sin^2 \alpha + \sin^2 \beta + \sin^2 \gamma = 2 when α,β,γ\alpha, \beta, \gamma are the angles a half ray makes with the positive directions of the axes.
