培养学生解题能力,应该从多方面入手,课本中介绍的常是基本方法,然而有些技巧性方法却能开拓学生思路另辟蹊径,在解函数题时,如能注意挖掘题目的隐含条件,利用“函数奇偶性”解题常能出奇制胜,以下举数例说明。 To cultivate students’ problem-solving abilities, we should start from many aspects. The basic methods are often introduced in textbooks. However, some skillful methods can open up students’ ideas to open up new paths. When solving functional problems, we can pay attention to the hidden conditions of the topic and use it. The problem of “function parity” can often be surprisingly successful. Here are a few examples.
