关于相对导数的概念

The Coneept of Relative Derivative

本文在函数的导数理论的基础上,引入相对导数,高阶相对导数及相对微分的定义。并给出实际意义上的解释。

On the basis of the derivative theory of function, this article leads to the definitions of relative derivative, higher relative derivative and relative differential and then Shows their practical applications.
