If $\sin (\alpha+\beta)=1, \sin (\alpha-\beta)=\frac{1}{2}$, then $\tan (\alpha+2 \beta)$ tan $(2 \alpha+\beta)$ is equal to: (A) 1 (B) $-1$ (C) zero (D) none of these
If $\cos \alpha+\cos \beta+\cos \gamma=\sin \alpha+\sin \beta+\sin \gamma=0$ then $\cos (\beta+\gamma)+\cos (\alpha+\beta)+\cos (\alpha+\gamma)$ is equal to (a) 1 (b) 0 (c) $-1$ (d) $\frac{1}{2}$
If $\sin \alpha+\sin \beta+\sin \gamma=3$, then $\cos \alpha+\cos \beta+\cos \gamma$ is (a) 1 (b) 0 (c) $-1$ (d) 2 (1) $2^{3} 0$ ?n
