极值法就是运用极限思维,使某些量的变化抽象成无限大或无限小去解决实际问题的一种解题方法.在高中物理解题过程中,有些题用一般的方法解比较繁琐,而用极值法常常使问题变得豁然开朗.在解答某些问题时,为了快速地得到问题的答案,我们通常选取所涉问题的两个比较特殊的状态,再比较特殊状态下的特征,根据特殊状态来判断中间过程的变化,可以使问题在短时间内得到
Extreme value method is to use the limit of thinking, so that some changes in the abstraction into infinite or infinitesimal to solve the practical problem of a problem-solving method in high school physics problem-solving process, some problems with the general method of solving more complicated, The extreme value method often makes the problem suddenly clear.When certain problems are answered, in order to quickly get the answer to the question, we usually select the two special states of the problem, and then compare the characteristics of the special state, According to the special status to determine the changes in the intermediate process, you can make the problem in a short period of time
