Apresentamos breve relato sobre o surgimento da Conchóide de Nicomedes como uma forma de se "solucionar" um dos três clássicos problemas da geometria grega - o da trissecção do ângulo e abordamos o uso desta nos primórdios da Geometria analítica e do Cálculo no século XVII. Introduzimos a conchóide geral e analisamos com detalhes propriedades geométricas das conchóides de uma parábola. Discutimos a existência de singularidades - cúspides e pontos múltiplos, relacionando-os à evoluta e às curvas paralelas a uma parábola. Utilizamos o computador e programas livres de geometria dinâmica e cálculo simbólico para visualizar, experimentar e conjecturar os resultados a serem provados. / Abstract: We approach here one of the mechanical curves: The Conchoid. A brief description of the historical background of the Nicomedes'Conchoid, introduced to "solve" the angle trisection, one of the three classical problems of Greek geometry is presented and its use in the early times of the Calculus and Analytic Geometry in the XVII century is also described. We introduce the general conchoid and analyse the conchoids of a parabola. The existence of singularities such as cusps and multiple points is discussed and related to the evolute and parallel curves of a parabola. We have used the computer and free symbolic calculus and geometry software in visualising, experiencing and conjecturing results to be proved. / Mestrado / Geometria / Mestre em Matemática

TITLE: Agebraic Curves in History and School AUTHOR: Bc. Tomáš Fabián DEPARTMENT: The Department of mathematics and teaching of mathematics SUPERVISOR: prof. RNDr. Ladislav Kvasz, Dr. ABSTRACT: The thesis includes a series of exercises for senior high school students and the first year of university students. In these exercises, students will increase their knowledge about conics, especially how to draw them. Furthermore, students can learn about two unfamiliar curves: Conchoid and Quadratrix. All these curves are afterwards used for solving other problems - some Apollonius's problems, Three impossible constructions etc. Most of the construction is done in GeoGebra software. All the tasks are designed for students to learn how to work with this software. The subject discussed is put into historical context, and therefore the exercises are provided with historical commentary. The thesis also includes didactic notes, important or interesting solutions of exercises, possible issues, mistakes and another relevant notes. KEYWORDS: conic, circle, ellipse, parabola, hyperbole, conchoid, quadratrix, trisecting an angle, squaring the circle, rectification of the circle, doubling a cube, Apollonius's problem, GeoGebra
