生活中存在着大量的不等关系.要解决这些问题,就必须研究与之相对应的数学式子——不等式.故此,不等关系的探索,不等式的性质的深入理解,不等式(组)的解法以及不等式的应用都是需要密切关注的.一、不等关系的规律探究例1你能比较两个数2 017~(2 016)和2 016~(2017)的大小吗?为了解决这个问题,我们首先把它抽象成一般形式,即比较(n+1)n和n~(n+1)的大小(n为正整数).然后我们从特殊的情形入手,通
In order to solve these problems, we must study the corresponding mathematical formula - inequality.Therefore, the exploration of unequal relationship, the in-depth understanding of the nature of inequality, the inequality Solution and the application of inequality are the need to pay close attention to A. First, the law of unequal relations Inquire Example 1 Can you compare the two numbers 2 017 ~ (2 016) and 2 016 ~ (2017) size? In order to solve this problem , We first abstract it into a general form, that is, compare the sizes of (n + 1) n and n ~ (n + 1) (n is a positive integer)
