利用克莱洛(Clairaut)方程求二次曲线

Utilize the Clairaut’s Equation to Ask the Conic Section

利用著名的克莱洛方程的几何意义求二次曲线方程,就是建立克莱洛方程的一般模型,进一步揭示出克莱洛方程的通解与奇解,从动直线与动点两个方面来认识曲线的结构.

Utilizing the geometry meaning of famous Clairaut’s equation to ask the conic section equation means to set up the general model of Clairaut’s equation,to reveal the general solution and singular solution of Clairaut’s equation,and to understand structure of curve with move driven straight linepieces of two respectis.
