圆锥曲线是中学数学重要内容,是高考必考的难点内容之一,这部分内容由于计算量比较大,方法灵活多变而使很多同学望题兴叹.在解题过程中如果能挖掘圆锥曲线的几何特征,用平面几何的方法解决圆锥曲线问题,问题变得简单明了.本文举例说明平面几何方法 Conic curve is an important part of high school mathematics, is one of the difficult part of the college entrance examination will be part of this part of the content due to the large amount of calculation, the method is flexible and so many students sigh .In the process of solving problems if you can tap the conic Geometric features, the use of planar geometry method to solve the conic problem, the problem becomes simple and clear.This article illustrates the plane geometry method
