用几何画板软件验证(sinx)'=cosx

Validation of (sinx)'=cosx By Geometer SketchPAD

导数是高等数学的主要内容。利用定义证明导数公式,由于要涉及极限运算,思路抽象,计算繁琐。用几何画板软件的绘图功能,从导数的几何意义出发,通过原函数上的点,绘制导函数的图象,对基本初等函数导数公式进行验证,为学生学习导数提供了一个新的认知视角和研究方法。

The Reciprocal is the main content in Higher Mathmatics.The derivative formul is aproved by the definition concering on the limit algorithm with abstract thinking and complicated calculation.On the function of Geometer SketchPAD,the reciprocal can be validated from the geometrical meaning of the Reciprocal by drawing the graph of the morphic the function on the original function to provide a new aspect method for students.
