The value of (sin 1°)/(sin 1ᶜ) where 1ᶜ represents 1 radian is
Elementary MathematicsTrigonometry
- AEqual to 1
- BLess than 1
- CGreater than 1 but less than 2
- DGreater than 2
Explanation
1ᶜ = 1 radian ≈ 57.3°, so the ratio is sin 1°/sin 57.3° ≈ 0.0175/0.8415 ≈ 0.021. The numerator is far smaller than the denominator, so the ratio is less than 1. Hence option (B) Less than 1.
