Machines for creating geometric curves and their application in teaching practice
Abstract
In this research, a brief historical review of mathematical machines and mechanisms is first presented, finally focusing on the two historical 17th century parabolographs designed and constructed by Bonaventura Franciscus Cavalieri and Frans van Schooten. The two mechanisms were analyzed, simulated and reconstructed. Through dynamic geometry software, extensions and possibilities of the mechanisms that are not apparent were sought. With apparent elements of the van Schooten parabolic graph, the local curvature of the drawn parabolic arc was calculated, The inverse tangent problem solved geometrically by the van Schooten parabolograph was formulated, solving essentially the corresponding differential equation. Confirmed mechanically the equivalence of the definitions of the parabola which they involve making them mechanically equivalent, By the mediation of the two mechanisms, the concept of parabola was learned to a section of the 10thgrade class which was divided into two groups. Two ...
