Evoluţia unor instrumente şi dispozitive geometrice utilizate în matematică, arhitectură şi construcţii (IV) – conice

Abstract

The ellipse, hyperbola and parabola are familiar to anyone who has studied analytical geometry in high school. They were known and used by Greeks since antiquity, in constructions and theoretical geometry. Nowadays, the conics are used even for modeling the movement of subatomic particles, satellites or galaxies. The purpose of this paper is to bring to your attention the definition and main characteristics of conics, to create exact and approximate figures using the ruler and the compass and to present various tools that can be built with conics. At the end of each chapter you can find computer generated figures and their source code that can be accessible at stefanandrei33ro@yahoo.com.
