化归与转化的思想既是一种数学思想,又是一种数学能力,在高中数学的学习中,它无处不在,比如,数形之间的转化,将函数与方程的转化,将空间问题转化到平面上解决,几何与代数之间相互转化,实际问题向数学问题的转化等.下面谈谈转化思想在中学数学解题中的几点应用.一、函数与方程的转化函数与方程是两个不同的概念,但它们之间有着密切的联系,一个函数若有解析表达式,那么这个表达式就可看成是一个方程.一个二元方程,两个变量存在着对应关系,如果这
The idea of transformation and transformation is not only a mathematical idea, but also a mathematical ability. In the study of high school mathematics, it is ubiquitous. For example, the transformation between numbers and shapes, the transformation of functions and equations, and the transformation of space problems. Transformation to the plane to solve, the transformation between geometry and algebra, the transformation of practical problems to mathematical problems. Here to talk about the application of transformation ideas in mathematics problems in middle schools. First, the function and equation of the transformation function and equation is Two different concepts, but they are closely related, if a function has an analytical expression, then this expression can be seen as an equation. A binary equation, there is a corresponding relationship between two variables, if this
