代换法是数学解题中一种常用的极为重要的方法之一,它是把问题中的—些量有目的的用另一些量来替换,使问题更容易得到解决的方法。灵活、巧妙地运用各种代换能起到转变形式、变换角度、转移知识点;使问题化难为易、化繁为简、变不知为已知的作用。它既功效奇特,又适用广泛,值得探讨。本文就代换的技巧作—个抛砖引玉的例谈,请同行指教。
Substitution is one of the most important and commonly used methods in mathematical problem solving. It is a method of replacing some of the problems with some other purposeful quantities purposefully to make the problem easier to solve. Flexible and clever use of a variety of substitution can play a transforming form, change perspective, transfer knowledge points; make the problem difficult for easy, complex and simple, I do not know known role. It is both peculiar in function and wide in scope and worth exploring. This article on the replacement of skills - a startling example, please peer advice.
