在证明条件等式时,由于所给条件不同,征题方法和技巧是多种多样的。对于初学者来说,一时难以全部掌握。能否和解一元二次方程那样,找到一种通用的方法(公式法)来证明条件等式呢?本文介绍一种通用的证法——基本量法。1.什么叫基本量法在数学问题中,虽然有时涉及到许多量,但其中有几个量是可以独立取值的,而其它量则是这些量的函数,当我们选定任意一组这样的量作基本量,那么问题就归结为研究各基本量之间的关系了。这种着眼于基本量解决问题的方法叫基本量法。
When proving the conditional equations, the methods and techniques of the questions are varied due to the different conditions given. For beginners, it is difficult to master all the time. Is it possible to reconcile the one-dimensional quadratic equation to find a general method (formula method) to prove the conditional equation? This paper introduces a general proof method—basic volume method. 1. What is the basic method In the mathematics problem, although sometimes involves a lot of quantity, but some of them can be independently valued, and other quantity is a function of these quantity, when we select any group The basic amount of quantitative measures, then the question boils down to the relationship between the basic quantities. This method of focusing on basic quantities to solve problems is called basic measurement.
