数学中的数和形是紧密相连的,两者缺一不可,数形结合就是建立数学问题的题设和结论的关系,通过数量关系和图形的巧妙结合,探索出解决问题的新思路。数形结合不仅是一种非常重要的解题方法,也是一种重要的数学思想,数形结合能够发挥代数和几何的优势,使复杂的问题简单化、抽象的问题具体化,还能够锻炼学生的思维能力。 The numbers and shapes in mathematics are closely linked. Both are indispensable. The combination of numbers and shapes is the relationship between the questions and conclusions of mathematics problems. Through the ingenious combination of quantity relations and graphics, new ideas for solving problems are explored. The combination of number and shape is not only a very important method of solving problems, but also an important mathematical idea. The combination of numbers and forms can give full play to the advantages of algebra and geometry, simplify the complex problems and abstract the problems, and can also train students. Thinking ability.
