Mathematics - Trigonometric Ratios & Identities Question with Solution | TestHub

2 radians is about $114.6^{\circ }$, so $\sin 2\approx 0.91>\sin 2^{\circ }\approx 0.035$. Also 2 radian is an obtuse angle, so $\tan 2<0$, while 1 radian is acute, so $\tan 1>0>\tan 2$. Hence A, B and C are true and D is false.
