摘要
多元复合函数由于其复杂的对应关系和变量定位的复杂性,给求导带来很大的困难,尤其在理顺函数关系的层次上更是容易混淆。因此从理顺对应关系出发,通过三个步骤,总结出一套通用性较强的求导方法,并进一步梳理了一些比较容易混淆的概念。
Finding derivative is hard due to the complexity of variables＇ orientation and correspondingly homologous relations within multivariable composite function. Specifically, it is common to have confusion in inter-function relationship. Thus, in this es- say I put forward a set of 3-step solution to differentiation with wide universality commencing from homologous relations. Besides, with the method of clarification, I further analyze some related concepts.
