在初中数学的函数教学中,函数图象的平移是师生都要面对的一种重要的几何变换问题,这类问题蕴含着数形结合、分类讨论等数学思想方法.为了让学生更好地认识与理解函数图象平移的规律,若使用几何画板进行直观演示,会起到很好的教学效果.尽管平移变换是几何画板的一项基本功能,但想要在几何画板的直角坐标系中用鼠标随心所欲地平移某个函数图象,并同步显示其函数解析式,对于广大数学教
In the function teaching of junior middle school mathematics, the translation of the function image is an important geometric transformation problem faced by teachers and students, and such problems contain mathematical thinking methods such as the combination of number and form, classification, etc. In order to make students better To understand and understand the law of function image translation, if the use of geometric drawing board for intuitive presentation, will play a very good teaching effect.Although the translation of the geometric transformation is a basic function board, but want to draw on the geometric board rectangular coordinate system In the mouse with the arbitrary translation of a function image, and simultaneously display its function analytic, for the majority of mathematics to teach
