数形结合思想是通过形象思维和抽象思维的结合,将繁琐的问题简单化、抽象的问题具体化,进而达到解题的最终目的。但在具体运用数形结合思想解题的过程中,还存在一些问题,比如缺乏对数形结合的了解、数学基础知识不扎实等。这些问题均会对解题造成影响。那么在实际解题的过程中,如何正确运用数形结合思想呢?下面结合例题进行阐述。一、数形结合思想的运用范围(1)集合。集合是高中数学最基础且简单的题型,一
The idea of combining numbers and shapes is to combine cursory and abstract thinking through simple and abstract cumbersome questions so as to achieve the ultimate goal of solving problems. However, there are still some problems in the process of solving the problem by using the combination of number and form, such as the lack of understanding of logarithmic combination and the lack of solid basic knowledge of mathematics. These problems will affect the solution. So in the process of practical problem solving, how to correctly use the idea of digital combination? The following combination of examples to elaborate. First, the use of numerical combination of the scope of thought (1) set. Set is the most basic and high school math problems and simple questions, one
