数学是解决物理问题的重要工具,新课标《考试大纲》也明确指出学生要有用数学方法处理物理问题的能力。用数学方法处理物理问题在高中物理教学中十分常见,历年的高考试题中也是层出不穷。其中最有代表性的就是用数学方法解决物理中的极值问题。本文拟以例说的形式细数解决物理极值问题的数学方法,其中包括二次函数法、三角函数法、几何法、图像法、均值不等式法等等。
Mathematics is an important tool to solve physical problems, the new curriculum “test syllabus” also clearly pointed out that students have the ability to use mathematical methods to deal with physical problems. Mathematical methods to deal with physical problems in high school physics teaching is very common, over the years the college entrance examination exam is also endless. One of the most representative is the use of mathematical methods to solve the problem of extreme physics. This paper intends to take the example of the number of cases to solve the mathematical problem of extreme mathematical mathematical methods, including the quadratic function method, trigonometric function method, geometric method, image method, mean inequality method and so on.
