Unit Circle: Radian Measure with Input Boxes

This example demonstrates the relationship between angles and radian measure on the unit circle with interactive input boxes. It involves core math concepts like the unit circle, radian measure, trigonometric functions, and angle measurement. The construction uses GeoGebra commands and objects such as Intersect, Circle, Rotate, Segment, and Textfield. It is suitable for high school mathematics education to help students visually understand the connection between radian measure and the unit circle, enhancing spatial reasoning skills.
