Prise En Main De Carmetal (1/2)
Prise en main de CaRMetal (1/2) Extrait du Les nouvelles technologies pour l'enseignement des mathématiques http://revue.sesamath.net/spip.php?article599 Prise en main de CaRMetal (1/2) - N°39 - mars 2014 - Date de mise en ligne : jeudi 13 fÃ©vrier 2014 Les nouvelles technologies pour l'enseignement des mathématiques Copyright © Les nouvelles technologies pour l'enseignement des mathématiques Page 1/13 Prise en main de CaRMetal (1/2) Pourquoi diable ce nom de « CaRMetal » ?... Explication Il faut bien le reconnaître, ce nom évoque plutôt la sidérurgie que la géométrie dynamique, et on peut considérer que c'est une maladresse de communication. Mais ce jugement hâtif mérite d'être nuancé car ce nom, une fois décodé, traduit très finement l'essence du logiciel. Notons d'abord que si c'est la sidérurgie qui vient à l'esprit (on pense naturellement au groupe ArcelorMittal, qui a fait la une des journaux), c'est une association malheureuse... En réalité, c'est à la forge que « Metal » fait allusion, selon une métaphore très répandue chez les développeurs : le code d'un programme est malléable comme l'acier et se travaille selon un processus analogue (on casse et on recolle pour forger). C'est dans cette veine que s'inscrit par exemple le projet SourceForge. Mais ce n'est pas tout. • CaRMetal dérive de C.a.R (Compass and Ruler = Compas et Règle), et en reprend la racine. • Restait à le distinguer par un suffixe, et ce n'était pas chose aisée. Or, à l'origine, ce qui distingue CaRMetal de C.a.R, c'est la façon de concevoir l'interface.

A Brief Tour to Dynamic Geometry Software Boyko B
A Brief Tour to Dynamic Geometry Software Boyko B. Bantchev February, 2010 What is dynamic geometry software? A dynamic geometry (DG) program is a computer program for interactive creation and manipulation of geometric constructions. A characteristuc feature of such programs is that they build a geometric model of objects, such as points, lines, circles, etc., together with the dependencies that may relate the objects to each other. The user can manipulate the model by moving some of its parts, and the program accordingly – and instantly – changes the other parts, so that the constraints are preserved. By contrast with programs that just create images, a drawing in a DG program is a visualisation of an abstract model (of geometric nature) and, in particular, provides a visual initerface for its manipulation. DG programs vary signiﬁcantly in their drawing capabilities, but they are all centred around geometric modelling. A geometric model may be used for visualising complex geometric data, for doing calculations – including symbolic, for building and testing geometric hypotheses, or for creating geometrically precise illustrations to be used in printed documents or on the Web. Model building in most DG systems starts with creating a set of independent, freely existing objects – usually points, and proceeds by constructing ones that are dependent on the former through being geometrically related to them. Most geometry programs currently in use are designed for planar geometry, but a few allow for spatial constructions as well. Some of the systems automate proving geometry theorems, or provide assistance in ﬁnding such proofs. Uses & features of DG programs Typical uses of DG programs are: • graphical presentation of geometry on the screen; • exploring geometric properties, testing hypotheses; • visualising complex data; • geometric reasoning; • illustrations in document preparation; • illustrations for the Web; • libraries for geometric programming.

Arxiv:1912.03489V1 [Cs.CG] 7 Dec 2019 of Metric (Covering the Degenerate Cases)
MOEBINV: C++ LIBRARIES FOR MANIPULATIONS IN NON-EUCLIDEAN GEOMETRY VLADIMIR V. KISIL Abstract. The introduced package MoebInv contains two C++ libraries for symbolic, numeric and graphical manipulations in non-Euclidean geometry. The first library cycle implements basic geometric operations on cycles, which are the zero sets of certain polynomials of degree two. The second library figure operates on ensembles of cycles interconnected by Moebius-invariant relations: orthogonality, tangency, etc. Both libraries work in spaces with any dimension and arbitrary signatures of their metrics. Their essential func- tionality is accessible in interactive modes from Python/Jupyter shells and a dedicated Graphical User Interface. The latter does not require any coding skills and can be used in education. The package is tested on (and supplied for) various Linux distributions, Windows 10, Mac OS X and several cloud services. 1. Introduction We present the Open Source package MoebInv [1, 2]|a research and educational tool for various geometric setups. Its domain, design and functionality have some unique features which are not available elsewhere. The code is symbiotically growing together with the research in the extended Möbius{Liegeometry [3], both|the code and the theory|benefited from this interaction. Functionality of the package is accessible from a C++ code and can be interactively used through Python/Jupyter shells and a dedicated Graphical User Interface (GUI). There is already a collection of well-established and reputable Open Source geom- etry software (GeoGebra [4], CaRMetal [5], Kig [6], Dr. Geo [7]) as well as commercial educational packages (The Geometer's Sketchpad, Cabri, Cinderella, NetPad). All of those are designed to work primary with the Euclidean geometry|the oldest archetypal mathematical theory.

An Extension of Möbius–Lie Geometry with Conformal Ensembles of Cycles and Its Implementation in a Ginac Library
Proceedings of the International Geometry Center Vol. 11, no. 3 (2018) pp. 45–67 An extension of Möbius–Lie geometry with conformal ensembles of cycles and its implementation in a GiNaC library Vladimir V. Kisil Abstract. We propose to consider ensembles of cycles (quadrics), which are interconnected through conformal-invariant geometric relations (e.g. “to be orthogonal”, “to be tangent”, etc.), as new objects in an extended Möbius–Lie geometry. It was recently demonstrated in several related papers, that such ensembles of cycles naturally parameterize many other conformally-invariant families of objects, e.g. loxodromes or continued fractions. The paper describes a method, which reduces a collection of conformally invariant geometric relations to a system of linear equations, which may be accompanied by one ﬁxed quadratic relation. To show its usefulness, the method is implemented as a C++ library. It operates with numeric and sym- bolic data of cycles in spaces of arbitrary dimensionality and metrics with any signatures. Numeric calculations can be done in exact or approximate arithmetic. In the two- and three-dimensional cases illustrations and ani- mations can be produced. An interactive Python wrapper of the library is provided as well. Анотація. В статті розглядається розширення геометрії сфер введене Софусом Лі. Нас цікавлять властивості інваріантні відносно дробово-лі- нійних (мебіусових) перетворень. Об’єктами розширеної геометрії Мебіу- са-Лі є ансамблі сфер взаємопов’язані наборами відношень інваріантних відносно мебіусових перетворень простору, наприклад ортогональність, дотичніть та ін. В недавніх публікаціях було показано, що такі ансамблі дозволяють природним чином параметризувати різні об’єкти пов’язані з дробово-лінійними перетвореннями, наприклад локсодроми або непе- рервні дроби.

Rene´ Grothmann Catholic University of Eichst¨attGermany e-mail: [email protected] web: http://www.rene-grothmann.de Abstract. C.a.R (Compass and Ruler) is an advanced geometry program similar to other programs for "dynamic geometry", but with numerous features going beyond that category of software systems. The aim of this paper is to outline the intentions of C.a.R., and to provide hints for the best use of this program. Keywords. Dynamic Geometry. Mathematics Subject Classiﬁcation (2010). 97G40 1. Geometry Doing geometry with compass and ruler looks out of date now, especially when done on paper as in the old days. Like handwriting and pencil arithmetic it is certainly a basic technique that has been important to our culture, but that has lost its meaning somewhat. This is undeniably true. Today, we use computer programs to draw, from simple function plotters to advanced CAD systems or realistic 3D rendering machines. But geometry is more than simple sketches. There can be no doubt that visual imagination is so basic that it cannot be learned early enough. It is one of the three columns of mathematics. Almost all mathematicians use it all the time, even in the most complex settings. To make mathematics, we use images in one, two or three dimensions, graphs of functions, curves and surfaces, as well as graphical representations of relations.

Contents This Lecture Concerns
Contents This lecture concerns : • The place of geometry in French educational system and its evolution from 1905 till now. • The benefits of using DGS in the classroom . • My discovering and use of JSXGraph • The problem of 3D Geometry (and my disillusions) • Some personal notes about the comparison between GeoGebra and JSXGraph, with regard to the production of web documents. Math teaching in France (mostly 20th century). Most European countries tried to adapt their educational system to modern times, specially in sciences, and particularly in maths. So French attempts are not isolated, but they are radical because of centralization. A lot of countries abandon to provinces, regions, counties, Länder, the authority to define programs and to apply them to councils. Some harmonization exists at the state level, but let us say that the system is more down-up than contrary. In France the top-down model is the rule. Although this is a bit changing now some internal organization in the ministry known as ‘Inspection Générale’ had all power to define what should be presented to pupils in primary and secondary schools and how it should be done. The seventies saw the victory of ‘structuralism’ and a kind of ‘bourbakization’ of math treaties and usual textbooks. A lot of web sites tell the whole story with great details., but unfortunately and understandably all of them are written in French and accessible only to interested readers who know the language or have good online translators. Here are some examples: http://michel.delord.free.fr/rb/rb-placegeom.pdf by Michel Delord http://www.univ-irem.fr/IMG/pdf/ensG.pdf https://www.imo.universite-paris-saclay.fr/~perrin/Livregeometrie/DPPostface.pdf but you can find a lot more about the same subject.

Carmetal : UNE GÉOMÉTRIE DYNAMIQUE ENRICHIE
EXPRESSIONS N° 35, septembre 2010, p. 165-272. CaRMetal : UNE GÉOMÉTRIE DYNAMIQUE ENRICHIE Yves MARTIN Université de la Réunion (LIM, EREDIM) Résumé – Ce texte pose un regard didactique sur l’utilisation des différents concepts que met à notre disposition le logiciel CaRMetal. Nous y abordons le sens que prend l’anticipation systématique de tous les outils, l’opérationnalité de l’a-modalité géné- ralisée, la pertinence augmentée de la manipulation directe et son extension aux structures finies, l’affranchissement du déterminisme avec le plongement des figures dans le temps de l’utilisateur, l’engagement direct augmenté qui en résulte ainsi qu’un un déterminisme enrichi rendu possible par la rencontre de l’aimantation et de la récursivité. Puis, avec son intégration du JavaScript, nous abordons des usages sco- laires spécifiques comme l’investigation algébrique avec la géométrie repérée dyna- mique. Nous terminerons en revenant sur le temps pour voir que l’animation respecte la temporalité dans laquelle les figures peuvent être plongées. Mots-clés : géométrie dynamique, anticipation, modalité, a-modalité, déterminisme, continuité, logique, booléen, récursivité, aimantation, réalité augmentée, géométrie repérée, algorithmique, programmation, JavaScript, Laborde, Kortenkamp, Hakenholz, CaRMetal, EIAH. Abstract. – The following paper gives a didactic account of the handling of the various concepts offered by the CaRMetal program. It helps us understand the meaning of the systematic anticipation of all the tools, the operationality of generalised a-modality, the pertinence coupled with direct manipulation and its extension to finite structures, the breaking away from determinism through figures immersed in the user’s time, the increased direct engagement resulting from it together with a form of enriched determinism made possible by the merging of magnetisation and recursivity.
