同样是一个数,如果跳出“抽象的数”这个圈子,则可联想到数轴、方程的根等等,当我们赋予它某种含义后,自然而然就找到了其几何背景,从而增进了对问题的理解.因此,新的数形结合的解法就此诞生了. 同样是一个几何问题,如果跳出“几何”这个圈子,联想到面积、方程等等,同样也找到代数的背景增进问题的解决. The same is a number. If you jump out of the “abstract number” circle, you can think of the number axis, the root of the equation, etc. When we give it a certain meaning, we naturally find out its geometric background, which enhances the problem. Understanding. Therefore, a new solution to the combination of number and shape was born. It is also a geometric problem. If we jump out of this circle of “geometry” and associate areas, equations, etc., we also find solutions to the problems of algebraic background enhancement.
