Which of the following relations is correct

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 $\left[ {0 \to \frac{\pi }{2}} \right]$.
