二次函数是中学数学的重点,也是难点.《几何画板》作为中学数学教学的得力工具,首先体现在对各种函数图象的制作上.用《几何画板》构造动态函数y=
The quadratic function is the focal point of middle school mathematics, and it is also a difficult point. “Geometric Sketchpad” is a powerful tool for middle school mathematics teaching. It is firstly embodied in the production of various function images. Constructing a dynamic function with “Geometric Sketchpad” y=
