This example demonstrates the unit circle and its application in trigonometry. Key mathematical concepts include the unit circle, trigonometric functions, and angles. Using GeoGebra commands such as Intersect, Circle, and CircleArc, points on the unit circle and angles are constructed to illustrate the graphs of sine, cosine, and tangent functions. Suitable for high school mathematics education and learning.

GeoGebra Commands & Parameters

  1. Intersect(xAxis, yAxis) → A
  2. Circle(A, 1) → c
  3. Intersect(c, xAxis, 2) → C
  4. Intersect(c, yAxis, 2) → E
  5. CircleArc(A, C, E) → d
  6. Point(d) → D
  7. Angle(C, A, D) → θ
  8. Ray(A, D) → f
  9. Segment(D, B) → g
  10. Tangent(C, c) → h,
  11. Intersect(h, f) → H
  12. Segment(B, D) → BD
  13. Point(g) → I
  14. Segment(A, B) → AB
  15. Point(AB) → J
  16. Angle(D, B, A) → α
  17. Segment(C, H) → HC
  18. Point(HC) → L
  19. Angle(H, C, A) → γ
  20. Segment(A, H) → AH

AI Drawing Prompt Reference

Draw a unit circle and mark its intersection with the coordinate axes. Take points on the circle, connect them to the center to form angles. Use arcs to represent angles and plot the sine, cosine, and tangent functions to show the relationship between angles and function values.
