Question

Which of the following statement is correct

Solution

Correct option is

sin 1 > sin 10, tan 2 < 0 and tan 1 < tan 2

Since 1 radian lies between 570 and 580 and sin 570 > sin 10, so sin 1 > sin 10. Again 1 radian is an acute angle and 2 radian is an obtuse angle, tan 1 > 0, tan 2 < 0, so that tan 1 > tan 2.
