Analysis of the offset to a parabola
Computer Aided Geometric Design, 1995Abstract Wei Lu has recently constructed a proper rational parameterization for the two-sided offset to a parabola—indicating that this locus, an irreducible curve of degree n = 6, is of genus 0. The theory of algebraic curves then requires that the parabola offset have 1 2 (n−1)(n−2) = 10 double points.

, 2023 Dal greco παραβολή, “collocazione di una cosa accanto a un’altra”, quindi “comparazione, similitudine”. La parabola è prima di tutto una traiettoria (Galileo) poi una sezione strutturale che si avvicina all’ottimale in termini sia di resistenza sia di rigidezza. Note le parabole in letteratura: narrazioni metaforiche per trasmettere un insegnamento o

Developing the concept of a parabola in Taxicab geometry
International Journal of Mathematical Education in Science and Technology, 2015 WOS: 000354282000007The aim of this study was to observe the development process of the concept of a parabola in Taxicab geometry. The study was carried out in two stages.

Parabolas have many interesting properties which were perhaps more well known in centuries past. Many of these properties hold only for parabolas, providing a characterization which can be used to recognize (theoretically, at least) a parabola. Here, we present a dozen characterizations of parabolas, involving tangent lines, areas, and the well-known ...

In the present paper, we propose a new definition of discrete parabolas, the so-called arithmetic discrete parabolas. We base our approach on a non-constant thickness function and characterized the 0-connected and 1-connected parabolas in terms of thickness function.

Given a parabola in the standard form corresponding to three points on the parabola, such that the normals at these three points concur at a point the equation of the circumscribing circle through the three points provides a tremendous opportunity to illustrate ‘The Art of Algebraic Manipulations’. The equation of the circle exists as a separate entity
