当点在圆锥曲线上时,点的坐标满足曲线方程,当点不在圆锥曲线上时,则点的坐标不满足曲线方程,在解题中如何应用点与圆锥曲线的这种位置关系
When the point is on the conic, the coordinate of the point satisfies the equation of the curve. When the point is not on the conic, then the coordinate of the point does not satisfy the equation of the curve. How to apply the positional relationship between the point and the conic
