This example demonstrates the relationship between trigonometric functions and the unit circle. Key mathematical concepts include trigonometric functions, unit circle, and angles. Using GeoGebra commands such as Circle, Point, Tangent, etc., it dynamically illustrates the properties of trigonometric functions. Suitable for high school mathematics education and learning.

  5. Line(O, P) → d
  6. Angle(Q_1, O, P) → α
  7. Segment(O, P) → a
  8. Segment(Y, P) → b
  9. Segment(P, X) → e
  10. Midpoint(a) → M
  11. Angle(P, X, O) → β
  12. Intersect(f, d) → Q
  13. Segment(O, Q) → h
  14. Segment(O, Q_1) → i
  15. Segment(Q, Q_1) → j
  16. Angle(Q, Q_1, O) → γ
