在前两节课的研究当中,学生已掌握了一些简单的不等式及其应用,并能用不等式及不等式组抽象出实际问题中的不等量关系,掌握了不等式的一些简单性质与证明,研究了一元二次不等式及其解法,学习了二元一次不等式(组)与简单的线性规划问题.本节课的研究是前三大节学习的延续和拓展.另外,为基本不等式的应用垫定了坚实的基础,所以说,本节课是起到了承上启下的作用.本节课是通过让学生观察第24届国际数学家大会的会标图案中隐含的相等
In the first two classes of studies, students have mastered some simple inequalities and their applications, and can use inequalities and inequalities to abstract the inequalities in practical problems, and grasp some simple properties of inequality and proof In this paper, we study the problem of linear inequality (group) and simple linear programming, which is the continuation and expansion of the first three sections of learning.In addition, the application of basic inequality A solid foundation, so that this class has played a role in the context of this lesson is to enable students to observe the 24th International Conference of Mathematicians implicit in the logo implied equal
