1课例解析数列是一种特殊的函数,是中学数学知识的重要组成部分.它在整个中学数学教学内容中,处于一个知识汇合点的地位,很多知识都与数列有着密切联系,过去学过的数、式、方程、函数、简易逻辑等知识在这一章均得到了较为充分的应用,尤其是加深了学生对函数概念的认识,使他们了解到不仅可以有自变量连续变化的函数,还可以有自变量离散 1 Case Analysis Series is a special function, is an important part of high school mathematics knowledge in the entire secondary school mathematics teaching content, is in a position of knowledge convergence, a lot of knowledge is closely linked with the sequence, learned in the past The numbers, equations, functions, simple logic and other knowledge are more fully applied in this chapter. In particular, students’ understanding of the concept of functions is deepened so that they understand that not only can there be continuous functions of independent variables, There can also be discrete arguments
