函数微积分导数函数图像
这个范例演示了如何通过移动点来直观理解导数函数图像的构造。核心数学概念包括导数、函数图像、上和下和（或黎曼和）、切线函数。作图要点——从下方『构造摘要』提炼用到了哪些 GeoGebra 命令/对象：Random, RandomElement, Point, Circle, Intersect, Vector；对象：list1, f, b, c, d, a, g, vert_A, A, line_A, circle_A, A_2, A_3, A_1, u_A, v_A, vert_B, B, circle_B, line_B, B_1, B_2, B_3, u_B, v_B, vert_C, C, C_1, circle_C, line_C, C_2, C_3, u_C, v_C, vert_D, D, line_D, circle_D, D_1, D_2。适合高中学段或微积分初学者使用。

AI 绘图提示语参考

绘制一个函数图像及其导数图像，通过随机生成点并绘制圆和线段来直观展示导数的概念。首先，在函数图像上随机选择几个点，为每个点绘制一个圆，然后找到圆与函数图像的交点，连接这些交点形成一条近似于切线的线段。通过这些线段和圆，展示函数图像的局部变化率，从而直观地理解导数的几何意义。
