圆锥曲线是高中数学的重要内容,在圆锥曲线中蕴藏着很多重要的结论和性质,如果我们能熟练掌握这些性质并加以推广,不仅能在解题中起到事半功倍的效果,而且能提高我们归纳推理、类比猜想的能力,为良好数学素养的形成奠定基础.2014年无锡市中学数学青年教师基本功大赛,在笔试环节遇到了下面这样一个题目(下文的例1),很多参赛者都感叹题目不易.以下是笔者结合自身
Conic is an important part of high school mathematics. There are many important conclusions and properties in the conic. If we can master and promote these properties, we can not only play a multiplier effect in solving problems, but also improve our inductive Reasoning, the ability to guess the analogy to lay the foundation for the formation of good mathematical literacy in Wuxi City, 2014 Middle School Maths Young Teachers Basic Skills Competition in the written test encountered such a topic (Example 1 below), many participants are lamented the subject is not easy The following is the author with their own
