立体几何微积分最值优化几何作图函数图像
①本范例演示圆锥内接圆柱的体积变化规律；②涉及核心数学概念包括立体几何、体积计算、函数关系；③构造要点：使用Point, Circle, Cone, Segment, Cylinder, Volume, PointIn, Plane, IntersectPath, Corner, Locus, Extremum等GeoGebra命令和对象；④适合高中数学教学和几何作图学习。

  9. Volume(g) → volumeg
  10. PointIn(xOyPlane) → PointxOyPlane_1
  11. Volume(a) → volumea
  12. PointIn(xOyPlane) → PointxOyPlane
  13. Plane(xAxis, zAxis) → j
  14. IntersectPath(j, g) → k
  15. Corner(k) → D, E, F, G
  16. IntersectPath(j, a) → p
  17. Corner(p) → H, I, J, K
