This example demonstrates the graph of the cosine function. It involves the core mathematical concept of trigonometric functions. Using GeoGebra commands such as Circle, Point, OrthogonalLine, Intersect, Segment, Arc, Translate, the graph of the cosine function can be constructed. Suitable for high school mathematics education and learning.

GeoGebra Commands & Parameters

  1. Circle((-2, 0), 1) → c
  2. Point(c) → A
  3. OrthogonalLine(A, y = 0) → f
  4. Intersect(y = 0, f) → C
  5. Segment(A, B) → g
  6. Segment(A, C) → h_4
  7. Segment(B, C) → h_1
  8. Arc(c, D, A) → b_1
  9. Translate(E, Vector[(b_1, 0)]) → E'
  10. Segment(E', G) → h_2
  11. Segment(E, E') → b_2
