## 圆锥曲线的伴随曲线研究

Conic Curve with Curve
Abstract: Conic curve with curve is one of the important contents of mathematics teaching.The so-called with curve is known for each point on the plane curve C M, take point P on the same plane and its corresponding, namely, M - P.As it moves, a point M on the curve C P generally also to accompany the point M and movement, second-hand P track for C ', is C 'for C with curve, M and P are concomitant point.In this paper, the main use of transforming, induction, analogy number form combined with the mathematical methods, such as, starting from the specific case, a detailed analysis, summarized the conic along with the application of curve and the problem solving method.
Key words: conic；Along with the curve；application；means.
