To talk about the construction method to solve the problem of the construction method of Yu Hongbing, roughly includes two aspects. For one, it is an auxiliary means to transform the proposition by constructing appropriate auxiliary quantities (such as graphs, functions, etc.) to help solve problems. Second, use the construction method to prove some existence propositions. This article introduces the application of construction method in two aspects through some examples. Let’s talk about the first thing first. Example 1 design...
