数形结合思想体现着数学的逻辑性,它将数学的两大概念,数量关系和空间形态有机地结合起来。在处理数学问题时必须要联系数与形两方面的内容,这样才能又好又快地解决问题。用好数形结合思想能够同时促进学生对数与形两方面知识的掌握。本文中笔者将具体讲解几类数形结合的方法,以期给读者以启发。1利用数学结合思想求解最值解析法一般以数轴或平面直角坐标系为依托,可以把各种式子的求值问题转化成为点与点之间的距
The idea of mathematical combination embodies the logic of mathematics, which combines the two concepts of mathematics, the quantitative relations and the spatial forms organically. In dealing with mathematical problems must be linked to the number and shape of the two aspects, so as to solve the problem soundly and quickly. With the combination of the idea of number and shape, we can simultaneously promote students' mastery of both knowledge and form. In this article, I will explain in detail the method of combining several types, with a view to inspire readers. 1 The use of mathematical combination of ideas to solve the most analytical method generally axis or plane Cartesian coordinate system as the basis, you can put various equations of evaluation problems into the point and the distance between the points
