During what degrees of rotation is a sine wave plotted?

• A. 0 to 180 degrees
• B. 0 to 360 degrees
• C. 90 to 270 degrees
• D. 45 to 360 degrees

Answer: (B)

The sine wave represents a continuous periodic function that is fundamentally based on the unit circle in trigonometry. One complete cycle of a sine wave corresponds to a rotation of 360 degrees. This means that the sine function starts from 0 degrees, rises to its maximum value at 90 degrees, falls back to 0 at 180 degrees, further declines to its minimum at 270 degrees, and completes the cycle back to 0 at 360 degrees. Therefore, the sine wave is fully plotted over the range from 0 to 360 degrees, capturing the entire cycle of the function and effectively representing all variations in its amplitude. Understanding that the sine wave progresses smoothly through each of these key points within the 360-degree range is crucial for applications in various fields such as physics, engineering, and signal processing, where waveforms are essential for analysis and interpretation.
