求解二元函数的最值,涉及到函数、不等式、线性规划、解析几何、向量等高中数学重点知识,更体现了函数思想、化归转化思想、数形结合思想和分类讨论思想等若干核心数学思想的应用.所以它是函数问题中的一大综合点,也一直是高考的热点.但“二元函数”的最值在中学没系统讲述,考生对这类问题求解比较困难,本文试图通过一道考题来探求“二元
Solving the binary function’s maximum value involves high school mathematics knowledge such as functions, inequalities, linear programming, analytical geometry, and vectors, and it also embodies some core mathematics such as function ideas, transformation and transformation ideas, mathematical combination ideas, and classification discussion ideas. The application of thought. So it is a comprehensive point in the function problem, and it has always been the focus of the college entrance examination. However, the value of the ”binary function“ is not systematically described in the middle school. It is difficult for candidates to solve such problems. Trying to explore ”binary" through an exam
