一、数形结合的要义数学家华罗庚说得好:“数形结合百般好,隔离分家万事休,几何代数统一体,永远联系莫分离”.几何图形的形象直观,便于理解,代数方法的一般性,解题过程的机械化,可操作性强,便于把握,因此数形结合思想是数学中重要的思想方法.所谓数形结合就是根据数学问题的题设和结论之间的内在联系,既分析其数量关系,又揭示其几何意义使
First, the mathematical combination of the meaning of a few figures Mathematical experts Hua Luogeng put it well: “Shape combination of good and bad, separated from each other everything off, geometric algebraic unity, always contact Mo separation.” Geometrical figure intuitive, easy to understand, algebra The generality of the method, the mechanization of the problem solving process, and the operability are strong and easy to grasp, so the combination of the number and shape is an important way of thinking in mathematics.The so-called number-shape combination is based on the internal relations between the problem and the conclusion of the mathematical problem , Not only analyze the relationship between the quantity, but also reveal its geometric significance
