运用函数的思想,可以建立函数关系,然后用函数的性质解决问题.运用方程的思想,可以通过构造方程(组),然后用代数方法研究方程(组)的解或解的情况,使问题获解.数形结合的思想是沟通直观与抽象的相互转化的重要数学思想.数学是以“数”与“形”作为研究对象的,而“数”和“形”是可以相互转化的.“数”和“形”之间的相互转化,有助于认识数学本质,活化数学思维,简化解题过程.分类与整合的思想能认识数学对象整 Using the idea of ​​function, we can establish the function relation, and then use the nature of the function to solve the problem.Using the idea of ​​equation, we can solve the problem by constructing equations (groups) and using algebraic methods to study the solution or solution of equations The idea of ​​combining numbers and forms is an important mathematical thought of mutual transformation between intuition and abstraction.Mathematics is based on “number ” and “form ”, and “number ” and “shape ”Can be transformed into each other. “ Number ”and “ Shape ”mutual transformation, help to understand the nature of mathematics, activation of mathematical thinking, to simplify the process of solving problems.Classification and integration of ideas can recognize mathematical objects
