“会当凌绝顶,一览众山小”,数学问题的简化和优化求解,取决于对数学问题的正确把握,解决问题的关键就是抓住问题的实质,找准解题切口,然后实施转化.转化是简化题意的重要手段,是巧解数学习题的一把利剑.在解题中巧妙使用转化,常常能达到一种曲径求捷通幽的解题效果.一、巧构公 “When you are extremely talented, you can see all the small hills.” The simplification and optimization of mathematics problems depends on the correct understanding of mathematical problems. The key to solving the problems is to grasp the essence of the problem, identify the problem-solving incision, and then implement transformation. Transformation is an important means to simplify the meaning of questions, and it is a sharp sword to solve a number of problem-solving problems. Using cleverly used transformations in problem solving can often achieve a kind of problem solving effect.
