本文结合高考中经常出现的二元函数的最值问题,阐述了求解的常用方法,即基本不等式、整体换元和数形结合法.高三学生学得辛苦,但由于缺乏对数学问题本质的认识,常常事倍功半,在重复与茫然的训练中效率不高.而我们教师可以通过自身的研究与探索,使得数学知识拎起来成一串、撒下去铺一片,这样就能让学生举一反三,让学生在收获的季节里,少些遗憾,多些欣慰!下面是本人针对二元函数的最值及其相关问题,进行了适
In this paper, the most commonly used in the college entrance examination of the binary function of the most value problems, describes the common method used to solve, that is, basic inequalities, the overall disaggregation and the number of combination method.Gao San students hard to learn, but due to the lack of understanding of the nature of mathematical problems , Often less effective in repetitive and lossless training efficiency is not high.And our teachers through their own research and exploration, making mathematical knowledge picked up into a string, sown to a shop, so that students can give top priority so that students harvest Of the season, less regrettable, more happy! Here is my best value for the binary function and its related issues, conducted a suitable
