“极限化”是重要的数学解题策略之一,是“有限与无限思想”在数学解题中的应用.有限与无限相比,有限显得具体,无限显得抽象,对有限的研究往往先于对无限的研究;反之,当积累了解决无限问题的经验之后,可以将有限问题转化成无限问题来解决.这种无限化有限、有限化无限的解决数学问题的策略就是极限化策略,它可以帮助我们快速探明问题的解决方向,轻松得到问 “Limit ” is one of the important strategies for solving math problems, and is the application of “finite and infinite thoughts ” in solving math problems.Limitations are infinitely concrete and limitlessly infinite, and for finite Research tends to precede the study of infinity, on the contrary, when accumulating the experience of solving infinite problems, the finite problem can be transformed into an infinite problem.This infinitely limited and infinitely limited strategy for solving mathematical problems is to limit Strategy, it can help us to quickly find the solution of the problem, easily get asked
