在高中数学中,等价转化可以说是无孔不入,灵活地应用它,可以把繁杂问题转化为简单问题,将抽象问题转化为具体的、直观的问题,把正面解决较困难的问题转化成从反面探求,从而使问题易于解决。在实际教学中,因限于篇幅,笔者就以下几个方面浅谈等价转化在解题中的应用。一、利用曲线的特征,将繁杂的计算问题转化为简单的计算问题 In high school mathematics, equivalence transformation can be said to be pervasive and flexible to apply it, transforming complex problems into simple ones, translating abstract problems into concrete, intuitive ones, and translating positive ones to more difficult ones into negative ones Explore, so that the problem is easy to solve. In the actual teaching, due to space limitations, the author on the following aspects of equivalent conversion in the problem-solving application. First, the use of the characteristics of the curve, the complex calculation of the problem into a simple calculation problem
