数形结合的思想,就是将复杂或抽象的数量关系与直观形象的图形在方法上相互渗透,并在一定条件下相互补充、转化的思想.一、函数与图象的对应关系、方程与曲线的对应关系在数学教学中,数形结合思想偏重于将某些抽象的数学问题直观化、生动化,能够变抽象思维为形象思维,这就有助于把握数学问题的本质.另外,由于使用了数形结合的方法,很多问题便迎刃而解且解法简洁.数形结合的思想方法应用广泛,常见的如求函
The idea of combining numbers and forms is the idea of interpenetrating the figures of complex or abstract quantitative relations with the images of visual images in a method and complementing and transforming each other under certain conditions.First, the correspondence between functions and images, equations and curves In maths teaching, the idea of combining figures and shapes emphasizes the visualization and vividness of some abstract mathematical problems and the change of abstract thinking into thinking of images, which helps to grasp the essence of mathematical problems.In addition, due to the use of The combination of the number of forms, many problems will be solved and the solution is concise. Combination of digital form of ideas widely used, such as the common letter
