运用数学知识来解物理问题,无疑是一种重要的方法。物理学离开了数学,就无法进行量的研究,就得不出规律性的知识,更谈不上解决实际问题了。但是利用数学知识处理物理问题。并不是“纯数学”运算,解题过程要受物理意义的制约。现举例如下: The use of mathematical knowledge to solve physical problems is undoubtedly an important method. If physics leaves mathematics, it cannot carry out quantitative research, and we cannot obtain regular knowledge, let alone solve practical problems. But using mathematical knowledge to deal with physical problems. It is not a “pure mathematics” operation, and the problem solving process is subject to physical meaning constraints. Here are some examples:
