EQUIVALENCE OF PARABOLA΄S DEFINITIONS WITHIN MATHEMATICAL MACHINES SIMULATED BY “GEOGEBRA”

Georgios K. Ntontos, Eugenia Koleza

Abstract


This paper aims to highlight two historical parabolographs and a third one that is at the design level and to prove the equivalence of the respective definitions of parabola they contain. Specifically, using the Geogebra math software, each mechanism is attempted to articulate another, so that by moving the cursor of the original mechanism to the common output of the two articulated mechanisms, the same parabola is drawn. This proves the equivalence of definitions of parabolic curve as well as of suitably articulated mathematical machines.
