Understanding the Trigonometric Functions
To solve the expression sin 2000 + cos 2000, we first need to understand the behavior of sine and cosine functions. Both functions oscillate between -1 and 1.
Analyzing sin 2000
- The sine function is periodic with a period of 2π (approximately 6.28).
- To find sin 2000, we can reduce 2000 modulo 2π.
- 2000 radians corresponds to approximately 318.31 full cycles (since 2000 / 2π ≈ 318.31).
- The angle can be simplified as 2000 - 318 * 2π, which gives us a remainder of approximately 5.76 radians.
Analyzing cos 2000
- Similarly, for cos 2000, we apply the same reduction.
- After calculating, we find that cos 2000 also corresponds to the same angle of around 5.76 radians.
Calculating sin(5.76) and cos(5.76)
- At 5.76 radians, which is slightly less than π (approximately 3.14), we are in the third quadrant.
- In the third quadrant, sin is negative, and cos is also negative.
Conclusion
- Hence, both sin(5.76) and cos(5.76) are negative.
- Therefore, sin 2000 + cos 2000 = sin(5.76) + cos(5.76) yields a negative value.
Thus, the correct answer is option 'D' - Negative.
