本文试图从宏观与微观两个角度来认识逆向思维在数学解题中的作用 一、宏观作用——用逆向思维制定解题策略 所谓解题的策略就是为实现解题目标而确定行动方针、方式和方法。策略的确定,对解题的顺利进行起着重要的作用。然而,一个正确 This article attempts to understand the role of reverse thinking in mathematical problem solving from both macroscopic and microscopic perspectives. 1. Macro-effects: Formulating problem-solving strategies with reverse thinking. The so-called problem-solving strategy is to determine the course of action and method for achieving problem-solving goals. And methods. The determination of strategies plays an important role in the smooth implementation of problem solving. However, one is correct
