圆锥曲线是高中数学的重要内容,它通常会以压轴题的形式呈现在各种考试中.平时学生训练的也不少,但得分率相对其他题型依旧比较低.究其原因,学生的运算能力以及对解析几何方法的深层次认识有待进一步的提高.解析几何最基本的方法是坐标法,即建立一个坐标系,将平面上的点与有序实数对建立起对应关系,从而实现图形与方程的相互转化,进而,我们可以通过方程来研究图形的性质.坐标法的优越性在于它利用了数可以运算的特点,把几何问题代数化. Conic curve is an important part of high school mathematics, it is usually presented in the form of pressure axis test in a variety of examinations. Usually students train a lot, but the scoring rate relative to other questions is still relatively low. The reason, the student’s operation Ability and analytical understanding of the deep understanding of geometric methods to be further improved.The most basic method of analytic geometry is the coordinate method, that is, to establish a coordinate system, the point on the plane and the order of real numbers to establish correspondence between graphics and Equation, and then, we can study the nature of the graph through the equation.The superiority of the coordinate method is that it takes advantage of the characteristics of the number of operations, the geometric problem of algebraic.
