| 摘 要： | 若一元函数存在导数,则可推得函数在某点连续,曲线呈光滑状态.而对多元函数来说,自变量在平面区域、空间区域甚至n维空间区域内变化,导数概念相对复杂.本文就导数概念的推广略加探讨.

| Abstract: | If there exists one-dimensional function and its derivative,we can come to the conclusion that function is continuous at certain point and its curve is smooth.As for multi-dimensional function,the concept of derivative is relatively complex because independent variables may vary in plane area,spatial area and even n-dimensional spatial area.The paper is designed to focus on the expansion of the concept of derivative. |
