High-Order Parametric Polynomial Approximation of Conic Sections
Constructive Approximation(2013)
摘要
In this paper, a particular shape preserving parametric polynomial approximation of conic sections is studied. The approach is based upon the parametric approximation of implicitly defined planar curves. Polynomial approximants derived are given in a closed form and provide the highest possible approximation order.
