n(≥5)边形的最大面极一般不能用边长的根式表示

The Createst Area of a polygon Generally Can't Be Represented by the radical-of The Sides

本文用Galois理论证明:多边形的最大面积一般不能用边长的根式表示。

In this paper, we proved the following result by the Galois theory: Thegreatest area of a n-gon (n≥5) generally can't be represented by the radicalof the sides.
