Lekalovian curves

Abstract

Unlike the curves that consist of the connections of circular arcs and are made with the help of a circle, in Lecalo curves, points lying on the curve are first made, and then they are connected with the help of a lecalo.

Lecalovian curves include curves called conic sections, that is, formed by the intersection of a right circular cone with a plane - ellipses, parabolas, hyperbolas, as well as involutes and sinusoids.
