解决数学问题,最难莫过于找到正确的思路,要想一下子得到简捷的思路就更难了。本文将介绍一种解决这一难点的新方法:“揉”。 所谓“揉”是指在解决问题的过程中,不是急于按照常规思路一步两步地往下解,而是在正式动手之前对题设条件(包括结论)之间进行充分的“揉合”,从而产生一些更有用的新条件和结论,以便更好地把握问题的实质,自然获得最佳的解题途径。 The most difficult way to solve math problems is to find the right ideas. It is even harder to think about simple ideas. This article will introduce a new way to solve this difficulty: “rubbing.” The so-called “kneading” means that in the process of solving problems, it is not eager to follow the conventional thinking to go down one step at a time, but before the formal hands-on approach, the “conditions” (including the conclusions) are fully “kneaded”. This will lead to some more useful new conditions and conclusions in order to better grasp the essence of the problem and naturally obtain the best solution to the problem.
