函数方程思想函数方程思想就是用函数、方程的观点和方法处理变量或未知数之间的关系,从而解决问题的一种思维方式,是很重要的数学思想。1.函数思想:把某变化过程中的一些相互制约的变量用函数关系表达出来,并研究这些量间的相互制约关系,最后解决问题,这就是函数思想。2.应用函数思想解题,确立变量之间的函数关系 Functional Equations Ideological Functional Equations is a very important mathematical thought that deals with the relationship between variables or unknowns using the perspectives and methods of functions and equations. 1. Function idea: To express some of the mutual control variables in a certain process of change by the functional relationship and to study the mutual restraint relations among these quantities, and finally to solve the problem. This is the function thought. 2. Application function problem solving, the establishment of the functional relationship between variables
