Consider the following:
- Isin 1° > sin 1ᶜ
- II... Which are not correct?
Elementary MathematicsTrigonometry
- A1 and 2 only
- B2 and 3 only
- C1 and 3 only
- D1,2 and 3
Explanation
Statement I is indeed false: 1 radian ≈ 57.3°, so sin1° < sin1ᶜ. However, statements II and III are truncated in the source, so they cannot be checked. The stored key D is therefore retained unchanged. Note: key disputed — verify against the official UPSC key.
