Understanding the Sine Wave
This animation traces a point moving around a unit circle and projects its vertical position onto a graph over time, revealing how the sine wave is generated. It highlights key features such as amplitude, period, and phase, showing how the smooth up-and-down motion of the circle translates into the repeating curve seen in graphs. Useful for students learning trigonometry or anyone studying periodic motion and wave behavior for the first time.
