研究定理的目的是为了更好地解答和讨论数学问题,注意定理的应用又是为了加强对定理的理解和记忆。在定理应用教学中,我们突出地抓了如下三件事,收到了较好的效果,现介绍如下: 一、扣住应用条件,注意应用层次定理的结论是其条件下的相对真理,忽视条件,盲目套用,必将导致谬误。因此,对于 The purpose of the research theorem is to better solve and discuss the mathematics problem, and pay attention to the application of the theorem to strengthen the understanding and memory of the theorem. In the theorem application teaching, we have prominently grasped the following three things and received good results. Now we introduce the following results: First, buckle the application conditions, pay attention to the application of the level theorem is the relative truth under its conditions, ignore the conditions Blindly applying it will certainly lead to delays. So, for
