数列是一类特殊的函数,它是定义在正整数或正整数的一个子集上的函数.因此把函数的观点、图像和性质有机地融入数列中,使数列与函数知识相互交汇,是一种重要的解决数列问题的方法.同时,高考对数列中蕴含的函数思想的考查越来越广泛,这样更显得函数知识在数列具有重要作用.对于那些复杂而难解的数列问题,应用函数知识或函数思想往往会使其变得简单易解.
A sequence of numbers is a special type of function that is defined as a function of a subset of positive integers or positive integers. Therefore, incorporating perspectives, images, and properties of a function into a sequence of numbers so that the sequence of numbers and function knowledge meet An important way to solve the problem of several series.At the same time, college entrance examination on the function of the sequence contained in the more and more extensive, so that the function of knowledge is more important in the series.For those complex and difficult to solve the sequence of problems, the application of functional knowledge Or function ideas tend to make it easy to understand.
