运用数形结合思想解决有关不等式的问题,是把代数式的精确刻划与几何图形的直观描述相结合,将数量关系和空间形式巧妙转化,可以使许多抽象概念和关系直观而形象,有利于解题途径的探求,使问题得到解决。运用这一数学思想,要熟练掌握相关概念和运算的几何意义及常见曲线的代数特征。本文结合具体示例展示了数形结合思想在不等式问题解决过程中的多种应用。
The solution to the problem of inequality by using the idea of number and form combination is to integrate the precise characterization of algebra and the intuitive description of the geometric figure. The quantity relation and the spatial form are skillfully transformed, which can make many abstract concepts and relationships intuitive and vivid, Exploration of the problem approach to solve the problem. Use this mathematical thinking, to master the relevant concepts and the geometric meaning of computing and algebraic features of common curves. In this paper, a concrete example is given to illustrate the various applications of the idea of number-shape combining in the process of solving inequalities.
