Matlab在函数辅助学习中的应用

Application of Matlab in Aided Function Learning

针对高中数学函数知识的抽象化问题,选择Matlab软件做为辅助学习工具,详细介绍了利用Matlab编程技术研究二次函数图像和斜面平抛运动性质的图形化显示的原理及具体实现。通过编程调整参数,给出了二次函数图像开口方向和斜面平抛运动末速度方向问题的多组图形化显示结果。实践表明,利用Matlab编程技术,可方便灵活地实现函数抽象问题的形象化,辅助对数学函数知识的深入理解。

In view of the abstraction of high school mathematic function knowledge, the Matlab software is used as an aided tool. This paper introduces in detail the quadratic function＇s image properties, inclined ball flat parabolic motion properties, methods and implementations based on Matlab language. The parameters can be automatically adjusted by Matlab programming. The multi-group graphical display results of quadratic function opening directions and inclined ball flat parabolic motion last speed directions are given. The practical application results show that the visualization of function abstraction problems can be implemented flexibly and assist the students to understand the mathematic function knowledge by using Matlab programming technology, and improve the research interesting for mathematic application problems based manual programming.
