导数作为高中数学新增内容,是解决许多数学问题尤其是与函数的单调性有关问题的有力工具·但是由于未能广泛了解导数知识产生的背景、深入理解导数的本质含义及有关性质,不能对相关应用问题进行有机整合而出现许多不应有的错误·本文举例说明导数应用需要注意的几个问题·一、 Derivatives, as a new addition to high school mathematics, are powerful tools for solving many problems of mathematics, especially those related to the monotony of functions. However, due to the lack of extensive understanding of the background of derivative knowledge and the profound understanding of the nature and nature of derivatives, it is impossible to There are many undeniable errors in the organic integration of related application problems. This article illustrates several issues that need to be taken into account in derivative applications.
