作为初学数学学习的重难点,函数最值求解问题一直是学生面临的一大数学难题,部分函数最值问题可以通过常规的代数方法进行解决,对于难以进行代数计算的问题则可以采用几何方法进行解决。本次研究将针对函数最值问题的特点,构建出几何模型,将其转换成为几何问题进行解决,该方法不仅直观明了,而且便于理解。 As a difficult task in the beginner's mathematics learning, the most value solving problem of the function has always been a major mathematical problem faced by students. The most value problems of partial functions can be solved by the conventional algebraic method. For the problems of difficult algebraic calculation, geometric problems can be solved solve. According to the characteristics of the most value function of the function, this study constructs a geometric model and transforms it into a geometric problem, which is not only intuitive but also easy to understand.
