This example demonstrates the relationship between the unit circle and trigonometric functions. Key mathematical concepts include the unit circle, trigonometric functions, and their graphs. Using GeoGebra commands such as Circle, Point, Intersect, and Angle, the construction highlights the properties of trigonometric functions. Suitable for high school mathematics education and learning.

GeoGebra Commands & Parameters

  1. Circle((0, 0), 1) → c
  2. Point(c) → A
  3. Intersect(xAxis, yAxis) → B
  4. Intersect(c, xAxis, 2) → C
  5. Angle(C, B, A) → α

AI Drawing Prompt Reference

Draw a unit circle centered at the origin with a radius of 1. Then place a point A on the circle, and find the intersection points B and C with the x-axis and y-axis, respectively. Finally, measure the angle α between point C, point B, and point A.
The prompt above was compiled from the original drawing commands and is for reference only.
