Which of the following is correct?

A
$\sin1^\circ>\sin1$
B
$\sin1^\circ<\sin1$
C
$\sin1^\circ=\sin1$
D
$\sin1^\circ=\frac{\pi}{18^\circ}\sin1$

✓

Answer

$\sin1^\circ<\sin1$

Solution:

we know that if $\theta$ increase then the value of $\sin\theta$ also increase

so, $\sin1^\circ<\sin1\Big[\because1\text{radian}=\frac{\pi}{180}\sin1\Big]$

Hence the correct option is (b).
