函数是高中数学最重要的内容之一,是贯穿中学数学内容的一条主线,因而对函数概念与性质的理解是高中数学教学的重中之重.但由于函数本身抽象性,使得许多同学在解题中经常会出现一些错误.下面对我们学习函数时经常犯的错误作一剖析.一、忽视定义域导致的错误定义域是函数的三大? The function is one of the most important contents of high school mathematics, and it is a main thread that runs through the middle school mathematics content. Therefore, the understanding of the concept and nature of the function is the most important task of high school mathematics teaching. However, due to the abstraction of the function itself, many students are There are often some mistakes in the questions. The following is an analysis of the mistakes we often make when learning functions. First, ignore the three major areas of the error definition domain caused by the definition of the domain?
