在复习圆锥曲线这部分内容时,要特别注意强化以下三种意识。一、数形结合的意识在解析几何中所涉及的曲线具有“数”与“形”的双重性,蕴含了数形结合思想,因此,数形结合是解析几何的基本思想方法。借助直观图形能使直线与圆锥曲线的位置
In reviewing this part of the conic curve, pay special attention to strengthening the following three kinds of awareness. I. The Consciousness of Combination of Numbers The duality between the “number” and the “shape” of the curves involved in analytic geometry implies the idea of combination of numbers and forms. Therefore, combination of numbers and forms is the basic method of thinking about analytic geometry . With intuitive graphics can make straight and conic position
