解数学问题时,人们常习惯于把它分解成若干个较简单的问题,然后再各个击破,分而治之.有时研究问题若能有意识地放大考察问题的“视角”,将需要解决的问题看作一个整体,通过研究问题的整体形式、整体结构,并注意已知条件及待求结论在这个“整体”中的地位和作用,然后通过对整体 When solving mathematics problems, people are often used to breaking it down into a number of simpler problems, then breaking them each other, dividing and conquering them. Sometimes research problems can consciously enlarge and examine the “perspective” of the problem and treat the problem to be solved as a Overall, by studying the overall form and overall structure of the problem, and paying attention to the known conditions and the status and role of the conclusion to be found in this “whole”, then
