If $\bar{a}$ and $\bar{b}$ are unit vectors and $\theta$ is the angle between them, then $|\bar{a}-\bar{b}| \cos \frac{\theta}{2}-|\bar{a}+\bar{b}| \sin \frac{\theta}{2}$ is (a) $\tan \theta$ (b) $-1$ (c) 0 (d) 1
If unit vectors $\hat{A}$ and $\hat{B}$ are inclined at an angle $\theta$. then $|\hat{A}-\hat{B}|$ is (a) $2 \sin \frac{\theta}{2}$ (b) $2 \cos \frac{\theta}{2}$ (c) $2 \tan \frac{\theta}{2}$ (d) $\tan \theta$
$\mathrm{a}$ and $\overline{\mathrm{b}}$ are two vectors of equal magnitude and $|\overline{\mathrm{b}} \| \overline{\mathrm{c}}|=4$. If $\overline{\mathrm{b}} \times(\overline{\mathrm{b}} \times \overline{\mathrm{c}})+4 \overline{\mathrm{a}}=0$ and If $\theta$ is the angle between $\mathrm{b}$ and $\mathrm{c}$, then $\sin 2 \theta+\cos 2 \theta$ equals (a) 1 (b) $-1$ (c) 0 (d) $\frac{1}{2}$
