MCQ
સમીકરણ $\cot \theta - \tan \theta = 2$ નો વ્યાપક ઉકેલ મેળવો.
- A$n\pi + \frac{\pi }{4}$
- ✓$\frac{{n\pi }}{2} + \frac{\pi }{8}$
- C$\frac{{n\pi }}{2} \pm \frac{\pi }{8}$
- Dએકપણ નહિ.
$ \Rightarrow $ $\tan 2\theta = \tan \frac{\pi }{4}$
$\Rightarrow 2\theta = n\pi + \frac{\pi }{4}$
$\Rightarrow \theta = \frac{{n\pi }}{2} + \frac{\pi }{8}$.
