初中学习平面几何,做了多少有关圆的问题?谁能数得清!几何性质背得滚瓜烂熟,定理定义也用得得心应手.添加一条辅助线,苦思冥索了好长时间的难题一下子就豁然开朗,那种喜悦,那种陶醉,真的溢于言表.今天,学了解析几何,又碰到了圆,然而解题方法、思维策略却大相径庭了.几何问题代数解,数形结合给圆的问题带来了新的内涵与活力.在新的背景下我们来讨论“圆”这个老话题,读者,能不能激活你更大的解题热情,能不能让你有更多的收获和提高呢?
Junior high school learning geometry, made a number of questions about the circle? Who can count it out! Geometrical backpacking, the theorem definition also used handy. Add a supporting line, hard wondering for a long time all of a sudden Suddenly, the kind of joy, the kind of intoxicated, really overflowing in words and expressions. Today, learning analytic geometry, but also hit the circle, but problem-solving methods, thinking strategies are quite different. Geometric problems Algebraic solutions, Brings new connotation and vitality.In the new context, we discuss the old topic of “round”, the reader, can activate your greater enthusiasm for solving problems, can you let you have more gains and improvements What?
