Which of the following statements are correct? A \( \quad \sin 1>\sin 1^{\circ} \)B \( \tan 2<0 \)C \( \tan 1>\tan 2 \)D \( \tan 2<\tan 1<0 \) |

Answer» Correct option is (A) sin 1 > sin 1° Relation between degree and radian is 180° = π radian ⇒ 1° = π/180 radian = 3.14/180 < 1 ⇒ 1° < 1 ∴ sin 1° < sin 1 ( ∵ tan θ is always increasing function) ∵ 2 > 0 ∵ 2 > 1 > 0 ⇒ tan 2 > tan 1 > tan 0 ⇒ tan 2 > tan 1 > 0 |
