Unit Circle, Radians, and Degrees by Evan Schilling (4)

This example demonstrates the relationship between angles, radians, and trigonometric values on the unit circle. It involves core mathematical concepts such as the unit circle, radian measure, degree measure, and trigonometric functions (sine, cosine, tangent). The construction uses GeoGebra commands and objects like Intersect (intersection), Circle (circle), Segment (line segment), Angle (angle), and CircleArc (arc). It is suitable for high school mathematics education to help students visually understand the definition and properties of trigonometric functions.
