Question: Which of the following relations is correct
[WB JEE 1991]
Options:
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} $
Show Answer
Answer:
Correct Answer: B
Solution:
The true relation is $ \sin 1>\sin 1{}^\circ $ Since value of $ \sin \theta $ is increasing $ [ 0\to \frac{\pi }{2} ] $ .
