જો $\cos \theta = \frac{\cos \alpha - \cos \beta}{1 - \cos \alpha \cos \beta}$ હોય,તો $\tan \frac{\theta}{2}$ ની એક કિંમત શું થાય?

  • A
    $\cot \frac{\beta}{2} \tan \frac{\alpha}{2}$
  • B
    $\tan \alpha \tan \frac{\beta}{2}$
  • C
    $\tan \frac{\beta}{2} \cot \frac{\alpha}{2}$
  • D
    $\tan ^2 \frac{\alpha}{2} \tan ^2 \frac{\beta}{2}$
