CircleTrigonometry
This example demonstrates the exact values on the unit circle. Key mathematical concepts include trigonometric functions and the Pythagorean theorem. Using GeoGebra commands such as Intersect, Point, and Circle, the relationship between points on the unit circle and angles is visually illustrated. Suitable for high school mathematics education and learning.

AI Drawing Prompt Reference

Draw a unit circle and mark a point X on it. Connect the center O to X and label the length b. Mark the angle α. Then draw the projection point A of X on the x-axis, connect A to points on the circle, and draw parallel line segments f and g to the x-axis, and h and i to the y-axis. Finally, draw the vector u from O to X, the vector v from X to the x-axis, and the vector w from X to the y-axis.
