平面向量在圆锥曲线中的应用,主要体现在向量的“工具”性上,即用向量语言来叙述一个解析几何的背景,只要把平面向量中有关坐标运算的基础打牢固,就能顺利解决这类问题.
The application of the plane vector in the conic section is mainly reflected in the “tool” property of the vector. That is to say, a vector language is used to describe the background of an analytical geometry. As long as the foundation of the coordinate operation in the plane vector is firmly established, the smoothness can be achieved. Solve this type of problem.
