这个范例演示了百分比变化的概念。它涉及的核心数学概念包括百分比计算和变化率。通过使用GeoGebra命令如Sequence、If、SelectedIndex等，可以动态展示不同情境下的百分比变化。适合初中及以上学生学习。

GeoGebra 命令及参数

  1. Sequence(Random[2, 3], m, 1, 110) → listposcorrect, {2, 2, 3, 2, 3, 3, 2, 3, 3, 2, 2, 2, 2, 3, 3, 2, 3, 3, 3, 2, 2, 3, 2, 3, 2, 3, 2, 3, 3, 3, 3, 3, 3, 3, 3, 2, 2, 2, 3, 3, 3, 2, 3, 2, 2, 3, 2, 2, 3, 2, 3, 3, 3, 3, 3, 2, 2, 3, 2, 2, 2, 2, 3, 2, 2, 3, 2, 3, 2, 2, 2, 3, 2, 2, 2, 2, 2, 3, 3, 2, 2, 3, 3, 2, 3, 3, 3, 3, 3, 3, 3, 2, 2, 3, 2, 3, 2, 2, 3, 2, 2, 3, 2, 2, 2, 3, 2, 2, 3, 2}
  2. If(exnum ≟ 4, 33, (numB / numA * 100)) → numC
  3. SelectedIndex(DropDown) → input
  4. Sequence(true, m, 1, maxstep) → listfixed
  5. Textfield(input1) → Eingabefeld1
  6. Textfield(input2) → Eingabefeld2
  7. If(exnum ≟ 3, 0.7, 1) → squaresize
  8. Sequence(O1 + (m * (0, squaresize)), m, 0, squarenum1 - 1) → l1
  9. Zip(Translate[Polygon[(0, 0), (squaresize, 0), (squaresize, squaresize), (0, squaresize)], P], P, l1) → v1
  10. Sequence(O2 + (m * (0, squaresize)), m, 0, squarenum2a - 1) → l2a
  11. Sequence(O3 + (m * (0, squaresize)), m, 0, squarenum3 - 1) → l3
  12. Zip(Translate[Polygon[(0, 0), (squaresize, 0), (squaresize, squaresize), (0, squaresize)], P], P, l2a) → v2a
  13. Zip(Translate[Polygon[(0, 0), (squaresize, 0), (squaresize, squaresize), (0, squaresize)], P], P, l3) → v3
  14. Sequence(O2 + (m * (0, squaresize)), m, squarenum2a, squarenum2a + squarenum2b - 1) → l2b
  15. Zip(Translate[Polygon[(0, 0), (squaresize, 0), (squaresize, squaresize), (0, squaresize)], P], P, l2b) → v2b
  16. Translate(Segment[(0, arrowheight), (squareabs - (2 * arrowabs) - squaresize, arrowheight)], O1 + (squaresize + arrowabs, 0)) → s1
  17. Translate(Segment[(0, arrowheight), (squareabs - (2 * arrowabs) - squaresize, arrowheight)], O2 + (squaresize + arrowabs, 0)) → s2

AI 绘图提示语参考

绘制一个展示百分比变化的动态图形，包含随机生成的序列，用不同大小的方块表示数值变化，并通过箭头和文本标注说明变化率，先画出基础方块和箭头，再根据序列动态调整方块大小和位置，最后添加文本说明百分比计算结果。
