数学学习中,数列和函数是重要的学习内容,数列是按一定次序排列的一列数.函数表示每个输入值对应唯一输出值的一种对应关系.数列也可以看作定义在正整数集或其子集上的特殊函数形式.学生通过对数列内容的学习,丰富了函数的内涵,同时也使得数列问题具有了更加清晰的认识和分析,在解决相关问题的时候能激发创新思维和意识.本文依托人教版教材,通过函数视角的分析,阐述了在数列问题思考时思所采用的函数方法,为解决相关问题提出思路.
In mathematics learning, sequences and functions are important learning contents. A sequence of numbers is a sequence of numbers arranged in a certain order. A function represents a corresponding relationship for each input value corresponding to a unique output value. A sequence of numbers can also be considered as a set of positive integers or The special function forms on its subsets. The students enriched the connotation of the function by studying the contents of the series. At the same time, it also made the series problem have a clearer understanding and analysis. It can inspire innovative thinking and consciousness when solving related problems. This article relies on the teaching materials of the People’s Education Press. Through the analysis of the functional perspective, this paper expounds the function methods adopted in the thinking of the series of questions and proposes ideas for resolving related issues.
