MCQ
Choose the correct answer. Which of the following is correct?
  • A
    $\sin1^\circ>\sin1$
  • ✓
    $\sin1^\circ<\sin1$
  • C
    $\sin1^\circ=\sin1$
  • D
    $\sin1^\circ=\frac{\pi}{18^\circ}\sin1$
✓

Answer

Correct option: B.
$\sin1^\circ<\sin1$
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 $(b).$
