一年一度的高考“既要重视考查中学基础知识的掌握程度,又要注意考查进入高校继续学习的潜能”,因此高考数学试卷中往往会出现一些以大学知识为背景的信息题,如函数的凹凸性、行列式等等.本文拟以2006年的高考题为例,谈谈拉格朗日定理在解题中的应用.拉格朗日定理若函数f(x)在[
Annual college entrance examination “should not only pay attention to master the mastery of basic knowledge in high school, but also pay attention to examine the potential to enter colleges and universities continue to learn”, so college entrance examination mathematics papers tend to appear in the background of the university knowledge of information problems, such as the function of Concavity and convexity, determinants, etc. This paper intends to take the 2006 college entrance examination questions as an example to talk about the application of Lagrange’s theorem in solving problems.The Lagrange theorem If the function f (x)
