在高三的一轮复习中,同学们不能只是简单地重复高一、高二所学的内容,满足于对概念、公式、定理的简单记忆,而应该在原来的基础上,适度挖掘、深刻理解概念、公式、定理的本质,从而提高复习效率,使解题事半功倍.本文以数列为例,谈谈如何把握知识的本质,从而使解题变得灵活、快捷.一、紧扣体现数列本质的量由等差(比)数列的概念,可知当这两种数列的基本量a1,d(q)确定后,整个数列便
In the third year of high school review, students can not just simply repeat the content of high school, sophomore learning to meet simple concepts, formulas, theorems, but should be based on the original, moderate excavation, a deep understanding of the concept , Formula, the essence of the theorem, so as to improve the efficiency of the review and make the problem-solving work more efficiently.This paper takes the sequence as an example to talk about how to grasp the essence of knowledge so that the problem-solving becomes flexible and quick. By the concept of arithmetic progression, we can see that when the basic quantities a1 and d (q) of the two kinds of series are fixed, the whole series
