本刊在2009年第7期刊登了刘兴明老师《二次函数在闭区间上的最值问题》一文,主要从对称轴与区间的位置关系进行分类讨论来研究最值问题.在解此类题时,若能充分挖掘题目的隐含条件,洞察问题的本质,就可以避免分类讨论或减少分类讨论的环节,从而简化解题途径.对此,本文就简化策略方面对其略作补充,供广大读者参考. This issue published in the seventh issue of 2009, Mr. Liu Xingming “quadratic function in the closed interval of the most value” article, mainly from the axis of symmetry and the location of the relationship between the classification discussed to study the most value problem. , If we can fully excavate the implicit conditions of the subject and perceive the essence of the problem, we can avoid discussing the classification or reducing the discussion of classification in order to simplify the way of solving the problem.Therefore, this paper briefly supplements the strategy to simplify Readers for reference.
