关于椭圆内接(外切)多边形的最大(最小)面积

On the Maximum/Minimum Areas of Inscribed/Circumscribed Polygons of Ellipse

本文运用多元函数极值的知识 ,计算出椭圆内接 (外切 )多边形的最大 (最小 )面积 ,以及此时椭圆内接 (外切 )多边形的特性。

By applying the limit value of multivariate function, the authors of this paper calculate the maximum/minimum areas of inscribed /circumscribed polygons of ellipse and comment on the relevant features of such polygons.
