Study of Double Circular Approximation of Planar Parameter Curve

本文综合运用几何作图和代数的方法来研究平面参数曲线的双圆弧逼近问题 :先使用几何作图方法研究双圆弧公切点的轨迹 。

This paper uses the methods of geometrical constructing and algebra synthetically to study the problem of double circular approximation of planar parameter curve: first use the method of geometrical constructing to study the loca of the common point of tangency of the two arcs, then use the method of algebra to get the equation of the loca of the common point of tangency and the common point of tangency which makes the curve have the best property of fair.
