数列是高中数学的重要内容之一,也是高考考查重点.它是特殊的函数,而函数又是高中数学的一条主线,所以数列常是命题者青睐的多个知识点交汇题,常与函数、不等式等知识结合考查.但学生在解数列问题时常遇到一些困惑,经常出错,却找不到错因.下面笔者就教学中学生遇到的几类常见错误进行剖析. Sequence is an important part of high school mathematics, but also the focus of college entrance examination test.It is a special function, and the function is a high school mathematics, so the sequence is often the proponent of many knowledge points confusing questions, often with the function, Inequality and other knowledge combined test.However, students often encounter some problems in the solution sequence problems, often mistakes, but can not find the wrong reason .In the following, the author analyzes some common mistakes encountered by teaching middle school students.
