最值问题常规思路我们可以归纳为如下几点:(1)问题三要素:解析式、常数、等号;(2)解题三部曲:先确定解析式、再放缩找常数、最后研究等号成立;(3)基本一要求:为确保等号成立,要求放缩一次.上述的思路确实为解决一些最值问题提供了可操作的方法,但也禁锢了我们的思维,随着最值问题的不断演变,对我们已经形成的一些常规方法形成了冲击,这就需要我们不断思考,研究问题的演变方向和特点,感悟解决问题的真谛.
We can be summarized as follows: (1) the three elements of the problem: analytical, constant, equal sign; (2) solve the trilogy: first to determine the type, and then zoom out to find the constants, the final study (3) Basic requirement: to ensure that the equal sign is established, it is required to deconsolidate the above ideas do provide a practical method for solving some of the most value problems, but also imprison our thinking, with the most The constant evolvement of the value issue has created an impact on some of the common methods that we have already formed. This requires us to constantly think about and study the evolving direction and characteristics of the problem and realize the true meaning of solving the problem.
