极限是数学中最基本、最重要的概念之一.极限是指在一个变化过程中,存在两个有关系的变量x和y,其中一个变量x无限接近(但不等于)一个定值(可能是常数,也可能是无穷大或无穷小)时,另一个变量y的变化趋势.若这个变化趋势是一个常数,则极限存在且等于这个常数,否则,极限不存在.这种在无限变化过程中考察变量变化趋势的思想就是极限思想.本文探讨一下“极限思想”在初
Limit is one of the most basic and important concepts in mathematics.Limit means there are two related variables x and y in a process of change, in which one variable x is infinitely close (but not equal to) a fixed value Is a constant, it may be infinity or infinitesimal), the trend of the other variable y.If this trend is a constant, the limit exists and is equal to this constant, otherwise, the limit does not exist.This study in the infinite change process The idea of variable trend is the limit idea.This paper explores the “limit idea” in the beginning
