同学们知道,解答数学问题离不开观察联想.如何根据问题的具体特征,恰当地进行观察联想,常常成为能否较快解决问题的关键.本文拟结合同学们解决几个圆锥曲线问题的思维历程,谈谈如何在解题中有效地实施观察联想.以资同学们参考.一、观察现象,联想本质有相当部分数学问题,往往是更一般问题的特列.在解答这类问题时,如果我们能够增
Students know that answer mathematics questions can not be separated from observation association.How to judge the association properly according to the specific characteristics of the question often becomes the key to whether the problem can be resolved quickly.This article intends to combine the students to solve the problem of several conic problems History, to talk about how to effectively implement observation in the problem-solving association. To refer to the students. First, the observation phenomenon, the nature of the association has a considerable part of the mathematical problems, often more general issues of special columns. In solving these problems, If we can increase
