当我们解(证)某些数学题运用常规思维受阻时,应迅速调整思维角度,另辟蹊径,逆向思维往往是可以考虑的一种方法.恰当地采用逆向思维,常能收到事半功倍的效果.本文举几例介绍,供学习时参考.
When we solve or prove that some mathematics questions are hindered by conventional thinking, we should quickly adjust the angle of thinking and take another path. Reverse thinking is often a method that can be considered. Correctly adopting reverse thinking can often result in a multiplier effect. Give a few examples for reference when learning.
