摘要
通过对方向导数和偏导数两者间区别与联系的论述,揭示了它们是同属于函数变化率问题的两个平行的不同的概念.
In this article the author presents the differences and connections between the directional derivative and the partial derivative, through which the fact that the two are two equivalent but different concepts in rate of change of function will be made clear.
