待定系数法是中学数学的重要思想方法,其应用比较广泛。为了更好地掌握此方法解决数学问题,笔者结合教学经验及参阅相关文献,分析待定系数法的基本思想,通过讨论待定系数的解题步骤及技巧,研究待定系数法的解题策略,最后给出简单应用,以供教学参考。
To be determined coefficient method is an important way of thinking in middle school mathematics, its application is more extensive. In order to better grasp this method to solve mathematical problems, the author combines the teaching experience and refer to the relevant literature to analyze the basic idea of the coefficient method to be determined by discussing the solution steps and techniques of the coefficient to be determined, to study the problem solving strategy of the coefficient method to be determined, and finally A simple application for teaching reference.
