2023年7月1日 · 8. We know that sin100° = sin(90° + 10°) = sin10° because the sine function has a periodicity of 360°. Therefore, our expression simplifies to: 2cos10° + sin10° - sin40° + sin80° 9. Now, let's consider the values of sin10°, sin40°, and sin80°. These angles fall within the first quadrant, where the sine function is positive.
