Demonstration of the Sine Function

This example demonstrates the graph of the sine function and its relationship with the unit circle. The core mathematical concepts involved include the sine function, unit circle, angles, and trigonometric functions. The construction uses GeoGebra commands like Angle, Segment, and objects such as α, a, b, A, c, B, d, e, f, g, text2, h, β, k, i, j, l to create angles, segments, and text elements. It is suitable for high school mathematics education, helping students visually understand the geometric meaning and properties of the sine function.
