数形结合是数学中重要的思想方法之一,它的实质抽象的语言与直观图形结合起来,可用代数手段研究几何问题,也可以用图形的直观研究代数或三角题,灵活运用数与形的转化,可以使待解(证)的问题化难为易,化抽象为具体,从而找到简捷巧妙的解法。下面用几个具体的例子,论迷《数形结合? The combination of number and shape is one of the important ways of thinking in mathematics. Its substantive and abstract language is integrated with intuitionistic graphics, algebraic means can be used to study the geometric problems, the graphical intuition can also be used to study algebra or trigonometry, and flexible use of numbers and shapes Transformation can make the problem to be solved difficult, easy to abstract as concrete, so as to find a simple and clever solution. With a few specific examples below, talk about "digital combination?
