This example uses rotation, angles, and polygons to explore the properties of trigonometric functions. Key mathematical concepts include trigonometric functions, angles, polygons, and loci. GeoGebra commands used include rotation, angle, polygon, and locus. Suitable for high school math education and students learning trigonometric functions.

GeoGebra Commands & Parameters

  1. Intersect(xAxis, yAxis) → A
  2. Circle(A, 1) → c
  3. Intersect(c, xAxis, 2) → B
  4. Rotate(B, α, A) → B'
  5. Angle(B, A, B') → β
  6. Polygon(A, B', C) → poly1, c_1, a_1, b'
  7. Tangent(B', c) → b,
  8. Segment(B', C) → n
  9. Distance(A, B') → distanceAB'
