数形结合,其实质是将抽象的数学语言与直观图形结合起来,使抽象思维和形象思维结合起来,实现抽象概念与具体形象的联系和转化,化难为易,化抽象为直观。文章就数形结合方法在函数问题、几何问题以及不等式问题中的应用进行了探讨。
The combination of number and shape, in essence, combines the abstract mathematical language with the visual graphics to combine the abstract thinking and the image thinking to realize the connection and transformation between the abstract concept and the concrete image. The paper discusses the application of the method of combination of numbers and forms in the problem of function, geometry and inequality.
