摘 要：函数的最值问题是我们在数学的学习过程中要探究的非常重要的一块内容.它不仅只在数学教学中需要解答的一些数学问题，还是我们经常解决一些实际问题的好方法.例如在工农业的生产、经济的管理和经济的核算中，我们就会常常面临一些在满足一定条件下怎样使产出最多、效益最高但投入最小等之类的诸多问题.在我们的日常生活中更是能够时常会遇到求用料要最省、效率要最高、利润要最大等的优化问题.然而这些生活和经济等的各方面问题一般都可以通过转变为数学中常常遇到的函数最值问题来分析研究，从而求得最优解转.这样做尤其是对那些要解决实际问题的人们来说特别的重要.它不仅可以梳理人们的思路，最重要的是它可以快速解决我们所面临的实际问题.我们将函数最值问题的解法分为一元函数和多元函数.这篇文章，主要通过对一元函数和多元函数最值问题进行分析，探讨他们各种不同的求解方法，从而表明函数的最值问题的研究的重要性. 关键词：函数；最值；导数；偏导数 Abstract: The most value problem is mathematical functions in the field of important research content. It not only in the teaching solving mathematical problems, and often used in solving practical problems. In the industrial and agricultural production, economic management and economic accounting, often encountered some solutions to meet certain conditions in how to produce the greatest, benefit highest but investment issues like the minimum. Life also often see for the most provinces, the highest efficiency and materials, such as maximum profit. And these life and economic problems generally can be transformed into the function in the mathematics problem for analysis and study, and then into the biggest (small) for function of the values of the problem is one of the most value function, this paper this especially for research of practical problems people is especially important. And the most value problem of solution function including a yuan function and multiple function, at the same time also have elementary and higher solution of the points. This paper mainly through elementary method to a from of most value of a circular function to research function, this paper discusses the solution of all kinds of different methods, including the most value function of importance, and get the most value solve the function of several methods and solving some problems that should be paid attention to. Key words: functions; the most value; higher solution; elementary method; differential序 言 函数是中学数学的主体内容，贯穿于整个中学阶段，而函数最值问题是函数的重要组成部分．处理函数最值的过程就是实现未知向已知、新问题向旧问题以及复杂问题向简单问题的转化，虽
