This example demonstrates the representation of hours, minutes, and seconds as fractions of time. Key mathematical concepts include fractions and time unit conversion. It uses GeoGebra commands such as CurveCartesian, Point, Sequence, Circle, Vector, and Segment for construction. Suitable for middle school and above students to learn time unit conversion and fraction applications.

GeoGebra Commands & Parameters

  1. CurveCartesian(P2 + (0.45; pi / 2 - t), t, 0, (2 * pi)) → curvaS
  2. CurveCartesian(P1 + ((0.82 * r); pi / 2 - t), t, 0, (2 * pi)) → curvaM
  3. CurveCartesian(P1 + ((0.6 * r); pi / 2 - t), t, 0, (2 * pi)) → curvaH
  4. Point(curvaH) → H
  5. Sequence(Segment[P1 + (2; s°), P1 + (1.9; s°)], s, 0, 360, 6) → marcasM
  6. Sequence(Segment[P2 + (0.6; s°), P2 + (0.55; s°)], s, 0, 360, 6) → marcasS
  7. Sequence(Segment[P2 + (0.6; s°), P2 + (0.5; s°)], s, 0, 360, 30) → marcasS2
  8. Point(Sequence[Point[curvaM, k / 60], k, 0, 59]) → M
  9. Circle(P2, 0.6) → circS
  10. Point(Sequence[Point[curvaS, k / 60], k, 0, 59]) → S
  11. Circle(P1, r) → circM
  12. Sequence(Segment[P1 + (2; s°), P1 + (1.75; s°)], s, 0, 360, 30) → marcasH
  13. Circle(P1, r) → circH
  14. Vector(P1, (1.04 * H) - (0.04 * P1)) → libreH
  15. Vector(P1, (1.04 * M) - (0.04 * P1)) → libreM
  16. Segment(P2, (1.04 * S) - (0.04 * P2)) → libreS
  17. Point(curvaH, (tiempo(4) - (12 * (tiempo(4) ≥ 12)) + tiempo(3) / 60 + tiempo(2) / 3600) / 12) → HH
  18. Point(curvaM, tiempo(3) / 60) → MM
  19. Point(curvaS, tiempo(2) / 60) → SS
  20. Vector(P1, (1.04 * HH) - (0.04 * P1)) → actualH
  21. Vector(P1, (1.04 * MM) - (0.04 * P1)) → actualM
  22. Segment(P2, (1.04 * SS) - (0.04 * P2)) → actualS

AI Drawing Prompt Reference

Draw a clock face representing time as fractions. At the center of the image is a dial with three concentric circular tracks representing the paths of the second, minute, and hour hands. The dial contains fine tick marks: hour marks every 30 degrees, minute marks every 6 degrees, and second marks every 6 degrees. Three hands extend from the center as line segments of varying lengths and directions, with the second hand shortest and hour hand longest. The hands are positioned dynamically based on time, illustrating the fractional conversion between time units. The overall design presents the mathematical relationship between time and circular motion.
