有些数学问题,若单独求解困难,甚至不能解出.或者虽可分别求出局部值,由于其值不止一个,运算既繁琐又易出错.若认真分析题意,仔细观察结构,把将要解决的问题看作一个整体,通过研究问题的整体形式,整体结构或作种种整体处理以后,达到顺利而又简捷地解决问题的目的.现举例说明如下: Some mathematics problems, if they are difficult to solve alone, can’t even be solved. Or although they can be found separately, because they have more than one value, the operation is both tedious and error-prone. If you carefully analyze the meaning of the problem, carefully observe the structure and solve the problem. The problem is regarded as a whole. After studying the overall form of the problem, the overall structure or the overall treatment, the objective of solving the problem can be achieved smoothly and simply. Here are some examples to illustrate:
