线性规划问题是不等式中的一大考点,其问题方式由最初正向问题(求线性目标函数的最值问题及平面区域面积问题)转变为逆向问题(求参数的范围问题),进而再与其它数学知识相交汇,发展为一类隐性问题,背景也越来越新颖、巧妙. Linear programming is one of the major test points in inequality, and the way of its problems is transformed from the initial positive problems (seeking the most value of the linear objective function and the problem of the area of ​​the plane area) to the reverse problem (finding the range of the parameters) Mathematical knowledge intersect, developed into a class of hidden problems, the background is more and more innovative and ingenious.
