测试改名0多边形三角函数微积分概率统计
本示例展示了如何通过动态几何构造矩形、正方形和三角形中的对角线关系，并探讨了正切函数与斜边长度的概率分布，同时计算了涉及这些三角形的斜边长度的不定积分。核心概念包括几何作图、垂心、正弦余弦定理、三角函数恒等式和积分计算。GeoGebra 中使用了 Polygon、Point 和 Segment 命令创建多个多边形和点对象，以便用户可以拖动顶点并实时观察变化。适合高中或大学一年级几何与微积分课程使用。

AI 绘图提示语参考

画面包含四行由单位正方形组成的网格：第一行从 x=1 到 x=15 共 14 个正方形，第二行从 x=0 到 x=15 共 15 个，第三行同样从 x=0 到 x=15 共 15 个，第四行从 x=0 到 x=4 共 4 个。所有正方形边长为 1，边平行于坐标轴，首尾相连形成不规则矩形区域，共 48 个多边形。
