数与形,是同一事物的两个不同方面,为了更好的研究事物,我们常常会从多个角度去寻找突破口,在数学中会将数量关系转化为成图形,也可以将图形转化成数量关系,而这种“数”与“形”的结合转化解题的方式,我们称之为数形结合思想.简单来说就是将抽象的数学知识与直观形象的图形充分结合起来,从而解决各种数学问题.但是一定要注意,“数”与“形”要结合起来,不能顾此失彼.图像虽然有直观形象的优势,但是也存在一些弊端,少 Number and form are two different aspects of the same thing. In order to study things better, we often look for breakthroughs from multiple perspectives. In mathematics, we can transform the quantitative relationship into a graph, and transform the graph into a quantity Relationship, and this “number ” and “form ” the combination of conversion problem-solving approach, we call it the combination of the number of forms with the idea simply put the abstract mathematical knowledge and intuitive image of the full combination of graphics, To solve a variety of mathematical problems, but we must pay attention to, Although the image has the advantages of intuitive image, but there are also some drawbacks, less
