The Exact Formula for the Ellipse Perimeter by Using Geometric Constructive Methodology

Abstract

Hiep-Son Nguyen

For many years since the ellipse was introduced to the mathematical world. Many theorems has been developed including formulas, but we could not come up the equation for the ellipse perimeter. We use the integral and numerical analysis methods to approximately measure the ellipse perimeter. The best known approximation formula of Sir. Srinivasa Ramanujan is consider to be the best and has most accurate result. This paper will demonstrate how I use geometry constructive method to establish the exact equation for the ellipse perimeter.
