Slider Animation
In collections Primary School Mathematics Collection
This example demonstrates the process of fraction multiplication using slider animation. Key mathematical concepts include fractions and multiplication. It utilizes commands such as Sequence, CircleArc, Segment, and CircleSector in GeoGebra.

GeoGebra Commands & Parameters

  1. Max(0, abs(t) - 5) → nt
  2. Min(nt, 100) → t1
  3. Max(0, nt - 100) → t2
  4. If(b, BA, AA) → C
  5. If(b, 1, (den1 - ts * (den1 - en1)) / den1) → f1
  6. Sequence(Segment[B, Rotate[B1, -f1 * 2 * π * i / den2, B]], i, 0, den2 - 1) → list2
  7. CircleArc(B, Rotate[B1, -2 * π * f1, B], B1) → f
  8. Segment(B, Rotate[B1, -2 * π * f1, B]) → a
  9. CircleSector(B, Rotate[B1, -f1 * 2 * π * en2 / den2, B], B1) → d
  10. Sequence(Segment[C, Rotate[C1, 2 * π * i / den3, C]], i, 1, den3 - 1) → list3
  11. If(b, (den2 - ts * (den2 - en2)) / den2, 1) → f2
  12. CircleSector(A, Rotate[A1, -f2 * 2 * π * en1 / den1, A], A1) → c
  13. Sequence(Segment[A, Rotate[A1, -f2 * 2 * π * i / den1, A]], i, 0, den1 - 1) → list1
  14. CircleArc(A, Rotate[A1, -2 * π * f2, A], A1) → e
  15. Segment(A, Rotate[A1, -2 * π * f2, A]) → g

AI Drawing Prompt Reference

Create an animation using a slider to demonstrate the process of multiplying fractions. Show the geometric meaning of multiplying two fractions, with sectors and arcs representing parts of the fractions, and segments connecting them to form the complete multiplication graphic. First draw the sectors and arcs for the fractions, then connect the parts, and finally use the slider to dynamically display the fraction multiplication process.
