抽象函数问题是学生学习函数时的一个难点,那么怎样突破因“抽象”而造成的解题障碍呢?“化生为熟”应该是一个重要的解题策略,利用我们所熟悉的函数、性质、定义、法则等,将抽象的问题熟悉化,从而打开解决抽象函数问题的通道.一、利用熟悉的和谐结构式化生为熟通过观察题目所给条件的结构特征,将之与所学过的熟悉内容建立联系,进行问题转化.
Abstract function problem is a difficult learning function when students, then how to break through the “abstract” caused by the problem-solving obstacles? “Metabolism is ripe” should be an important problem-solving strategy, we are familiar with The function, the nature, the definition, the law and so on, will abstract the familiarization of the question, thus opens up the passage which solves the abstract function question.First, uses the familiar harmonious structure to become familiar by observing the structure characteristic that the question gives the condition, Have learned the familiar content establish contact, carry on the question transformation.
