MCQ
$\sum\limits_{\lambda = 1}^{10} {{{\sin }^{ - 1}}\left( {\sin \left( {\lambda \pi - \frac{\pi }{6}} \right)} \right)} $ મેળવો.
- A$\frac{{5\pi }}{3}$
- B$\frac{{\pi }}{2}$
- ✓$0$
- D$5\pi$
$ = \sum\limits_{n = 1}^5 {{{\sin }^{ - 1}}\left( { - \sin \frac{\pi }{6}} \right) + \sum\limits_{n = 1}^5 {{{\sin }^{ - 1}}\left( {\sin \frac{\pi }{6}} \right)} } $
$ = - \frac{{5\pi }}{6} + \frac{{5\pi }}{6} = 0$
