In this topic you will learn about the most useful math concept for creating video game graphics: geometric transformations, specifically translations, rotations, reflections, and dilations. A practical voltage source can be transformed into an equivalent practical current source and similarly a practical current source into voltage source. Abstract: This lab demonstrates how bacteria can become antibiotic resistant. You will learn how to perform the transformations, and how to map one figure into another using these transformations. Here's how to do it. Khan Academy is a 501(c)(3) nonprofit organization. I was wandering if the Khan Academy content team could put together a lesson on transformers. Our mission is to provide a free, world-class education to anyone, anywhere. Written by Willy McAllister. Khan Academy. La pédagogie inversée de la Khan Academy C’est en voulant aider sa cousine Nadia à réussir un examen de mathématique que le financier pakistano-américain Salman Khan conçoit en 2009 un dispositif pédagogique au succès aussi spectaculaire qu’intrigant, symbole d’un profond remaniement des conceptions pédagogiques suscité par les opportunités du web. Working in teams, each team uses an unidentified plasmid that is either kanamycin-resistant or ampicillin-resistant and could possibly also code for the gene for green fluorescent protein (GFP). This source transformation method can also be used to convert a circuit from […] Appliquer une rotation dans le plan repéré en utilisant l'outil interactif, Construire l'image d'une figure par une rotation de centre quelconque, Image d'un point par une rotation dans le plan repéré, Appliquer une rotation de centre un point quelconque du repère, Construire l'image d'une figure par une symétrie axiale, Appliquer une symétrie axiale dans le plan repéré en utilisant l'outil interactif, Image d'une figure par une symétrie axiale dans le plan repéré, Image d'une figure par une symétrie axiale dont l'axe est une droite d'équation donnée, Les symétries axiales dans le plan repéré, Aucune vidéo ou article n'est disponible dans ce module, Les propriétés des isométries en application, Une suite d'isométries par laquelle telle figure est l'image de telle autre, Construire l'image d'une figure par une homothétie avec l'outil interactif, Image d'un point par une homothétie dans le plan repéré, Image d'un triangle par une homothétie dans le plan repéré, Figures invariantes dans une rotation de 180° - exemples, Construire un quadrilatère connaissant son centre de symétrie, Construire un quadrilatère connaissant ses axes de symétrie, Reconnaître si une droite est un axe de symétrie d'un polygone, Image d'un quadrilatère par une symétrie axiale, Trouver la translation dans laquelle une figure est l'image d'une autre, Trouver la rotation dans laquelle une figure est l'image d'une autre. When using a voltage source, it can be assumed to be 1V for simple calculations.
