摘要
本文应用导数理论,提出了相对导数的概念,并说明相对导数的实际意义。在此基础上,研究了相对导数的某些运算法则,并给出了它们的详细证明.此外,还研究了反函数的相对导数.最后给出了高阶相对导数的定义,并通过实例加以说明.
In this paper,derivative theory is uscd to introduce the concept of relative derivative, and we show practical meaning of relative derivative.Based on this,some operational rules of relative derivative are studicd,and their detailed proofs are given.Morecver,relative deri- vative of inverse function is also studied.Finally,the definition of higher relative derivative is given.Further,we give an interpretation by an example.
