在知识交汇处命题,是高考命题的基本思想之一,也是高考命题的一大热点.线性规划的本质是数形结合,而数形结合又是高中数学的重要思想方法,因此,在高考各地的模拟试题中,与线性规划交汇的数学问题受到命题者的亲睐.这类问题与方程、函数、向量、不等式、概率等知识内容交叉渗透,自然地交汇在一起,可考查综合运用数学知识分析、解决问题的能力.本文试作分类例说. Proposition in the intersection of knowledge is one of the basic ideas of the college entrance examination proposition, but also a hot topic of the college entrance examination proposition.Linear planning is the nature of the combination of several forms, and the combination of number and shape is an important way of thinking in high school mathematics, therefore, , The math problems meeting the linear programming are favored by the proponents.These problems cross with the equations, functions, vectors, inequalities, probabilities and other knowledge contents naturally and can be combined to test the comprehensive use of mathematical knowledge Analyze and solve problems.
