数形结合思想是一种非常重要的数学思想。数形结合通过数与形之间的对应和转化来解决数学问题,它包含“以形助数”和“以数解形”两个方面,兼有数的严谨与形的直观,利用它可使复杂问题简单化、抽象问题具体化,简化解题过程。但在解题过程中如何进行数形结合呢?哪些题型可以应用数形结合呢?本文从以下几个方面进行阐述。一、利用数形结合思想解决与方程的根有关的问题 The idea of ​​combining numbers and shapes is a very important mathematical idea. Mathematical problems are solved by the combination of numbers and shapes through the correspondence and transformation between numbers and forms. The mathematical forms contain rigorous and visual intuitions of both numerical and numerical solutions, Use it to simplify complex problems, abstract the problem of materialization, to simplify the process of solving problems. However, in the process of solving problems how to combine the number of forms? What kind of questions can be applied to form the combination? This article from the following aspects. First, the use of numerical combination of ideas to solve the problem with the roots of the equation
