  • Which of the following is correct? A. sin 1°> sin 1 B. sin 1°< sin 1 C. sin 1° = sin 1

Which of the following is correct?

A. \sin 1 ^{\circ} > \sin 1\\\\

B. \sin 1 ^{\circ} < \sin 1\\\\

C. \sin 1 ^{\circ} = \sin 1\\\\

D.\sin 1^{\circ}=\frac{\pi}{18^{\circ}} \sin 1

[Hint: 1 radian = 180 ^{\circ} \pi = 57 ^{\circ} 30'approx.]

 

Answers (1)

The answer is the option (b).

 If  ~ \theta  increases then the value of \sin \theta also increases.    \\\\

 

So, \sin1^{\circ}<\sin 1  

Hence, b is correct.
