1问题引入在例1中,综合推理(或传统解法)的方法不仅显得有点“过时”,而且还特别繁;对此,笔者将作一个对比,以此提出问题:本题的向量解法的快捷与传统方法的艰涩形成一个鲜明的对比,在新课程标准实施过程中,如何对待原来的综合推理的方法与新引进的向量的解题方法的地位?图1例1 1 Problem introduced in Example 1, the method of synthetic reasoning (or traditional solution) not only appears a little “outdated”, but also particularly complicated; In this regard, I will make a comparison, in order to raise the question: the problem of vector solution is quick and The traditional method of forming a sharp contrast, in the process of the implementation of the new curriculum standards, how to deal with the original method of comprehensive reasoning and the introduction of new vectors to solve the status of the problem?
