easy
આપેલ પૈકી ક્યો સંબધ શક્ય છે ?
A
$\sin 1 < \sin 1^\circ $
B
$\sin 1 > \sin 1^\circ $
C
$\sin 1 = \sin 1^\circ $
D
$\frac{\pi }{{180}}\sin \,\,\,1\, = \sin \,\,\,{1^o}$
Solution
(b) The true relation is $\sin 1 > \sin 1^\circ $
Since value of $\sin \theta $ is increasing $\left[ {0 \to \frac{\pi }{2}} \right]$.
