Pythag Proof. Alberta grade 10 math curriculum. How to Learn Math: For Students. Who is this course for? This course is designed for any learner of math and anyone who wants to improve their relationship with math. The ideas should be understandable by students of all levels of mathematics. Parents who have children under age 13 and who think their children would benefit from some of the course materials should register themselves (i.e., parent's name, email, username) for the course.
The parent may then choose to share course materials with their child at their own discretion. What is the course structure? The course will consist of six short lessons, taking approximately 20 minutes each. The lessons will combine presentations from Dr. What is the pace of the course?

What humanity could achieve if it weren’t galloping in front of computer screens THE loony music video “Gangnam Style” surpassed two billion views on YouTube this week, making it the most watched clip of all time. At 4:12 minutes, that equates to more than 140m hours, or more than 16,000 years. What other achievements were forgone in the time spent watching a sideways shuffle and air lasso?
It took 50m man-hours to complete the “supercarrier” USS Gerald Ford last year. JUMP Math. Math Worksheets | Dynamically Created Math Worksheets. Geometry: An Interactive Journey to Mastery. Today, geometry’s core skills of logic and reasoning are essential to success in school, work, and many other aspects of life. Like other math fields, geometry teaches us how to think. It leads students to uncover new truths based on already established ideas and facts. It requires us to test and examine the conclusions of others. It teaches us to lay out our thinking clearly, describing each step so that others can follow along and verify our results. This systematic way of thinking is essential in many fields.
In fact, the great Greek scholar Euclid demonstrated just how much you can do with logic. In short, geometry is among the great intellectual feats of humankind. Botanists use the geometry of triangles to estimate the heights of trees. With its powerful blend of intellectual accomplishment and practical application, it’s no wonder that most schools consider geometry a core subject.

Deux diplômés en génie informatique font fureur, avec l’application ... - Le Réseau des diplômées et diplômés de l'Université de Sherbrooke. 28 mai 2014 Diane Bergeron Aussitôt dévoilé, Slice Fractions est devenu le chouchou d’Apple. L’équipe de rédaction de la multinationale l’a placé en vedette sur son site de ventes en ligne d’applications pour ses produits mobiles. Ses créateurs, Dany Joly (Génie 2006) et François Boucher-Genesse (Génie 2006), n’auraient pu espérer meilleure visibilité pour le lancement de leur jeu qui aide les enfants à comprendre les fractions.
«D’être nommé l’application par excellence d’une semaine, nous a propulsé au 1er rang des téléchargements mobiles au Canada et au 2e rang aux États-Unis. Ça a complètement changé notre mise en marché», a confié François Boucher-Genesse à la journaliste Denise Proulx du Canal Argent. Slice Fractions, est le premier produit de la firme Ululab, lancée en 2012 par François Boucher-Genesse, Jean-Guillaume Dumont et Dany Joly. Information complémentaire Ululab.

Looking for something to watch this weekend? Xavier Amatriain can help. As a computer scientist at Netflix in California, he develops the recommendation system for the company’s online streaming service. Say you just watched last year’s animated adventure film Escape From Planet Earth. If you enjoyed it , Netflix might suggest you check out the older adventure movie Spy Kids 2: The Island of Lost Dreams.
Netflix makes these suggestions using a series of mathematical steps, or algorithms, designed by Amatriain and his team. The system analyzes your viewing habits to figure out your likes and dislikes, then comes up with movie picks just for you. ScienceWorld: How did you become interested in this work? SW: How does Netflix figure out what a particular person likes? SW: How do the recommendation algorithms work?
SW: What’s most fun about your job? SW: What would you tell someone who wants a job like yours? This article originally appeared in the May 5, 2014 issue of ScienceWorld magazine. Parents 3.0 – Les mathématiques sont-elles solubles dans le numérique ? Tracer en ligne des fonctions mathématiques, Online Function Grapher. Plus besoin de calculatrices scientifiques ou de programmes abscons pour tracer facilement des fonctions mathématiques. Online Function Grapher permet de tracer sur un repère en 2D les fonctions mathématiques de son choix directement dans son navigateur et de récupérer le dessin sous la forme d’une URL ou d’une image à télécharger.
L’apprenti mathématicien devra simplement indiquer une fonction f(x)= suivie d’une expression reconnue par l’application. Les fonctions indiquées sont tracées immédiatement dans une couleur particulière et viennent s’ajouter à celles qui ont déjà été calculées. On peut bien entendu effacer la feuille de traçage pour revenir à zéro. Les fonctions sont éditables, masquables, on peut utiliser des niveaux de parenthèses, les fonctions mathématiques les plus courantes sont reconnues.
Il faudra simplement se familiariser avec la syntaxe de l’application qui est clairement expliquée dans l’aide. L’application ne reconnaît qu’une variable (x). Interactive Trigonometry. Changing the triangle The black circles (each corner) can be moved by dragging anywhere within the left box. Fixing the right angle using the red button in the "SOH CAH TOA" tab means that whichever corner you drag, the triangle will remain locked into a right angle. Known glitch: sometimes the locking is out by a degree due to a rounding error in the program. Unfortunately for now you'll just have to be aware and resize the triangle slightly. What does each tab do? Switching Between Radians and Degrees It couldn't be easier! Generating Questions For the "SOH CAH TOA" tab, you must ensure you have a right angle at either A, B or C before a question will appear. When a question is generated, it will show the minimum amount of information needed to complete the question, and hide the rest.
The questions are generated at random with values from the triangle on the left so have fun questioning yourself until you know trigonometry like the back of your hand! Glitches. Great Games, Apps, and Sites for Geometry. Functions. Fork in the Road puzzle. Question: You're on a journey to the picturesque Truthsville, where all the residents tell the truth all the time, but come to a fork in the road. One way leads to Liartown; a nasty place where everyone lies all the time, and the other to Truthsville, but the sign is broken and you don't know which way to go!
Help is at hand, there's a resident from each town at the junction. The puzzle is this: You may ask one question to either resident (not both), and the answer will tell you which way Truthsville is. What should the question be? Bear in mind that one will always lie, and the other always tell the truth, but you are unaware which is which. Answer: (click to show) You must ask either one "what would the other person say?
" This plays on a simple rule of arithmetic: a positive times (and) a negative is always negative. La semaine des mathématiques. Dans le cadre de la troisième édition de la Semaine des mathématiques du 17 au 22 mars 2014, universcience.tv propose une sélection de films sur les maths dans l’histoire des sciences et sur les applications de cette discipline. Cette année, le thème de la Semaine des mathématiques - Mathématiques au carrefour des cultures, met l’accent sur les liens féconds existants entre les mathématiques et les autres disciplines (physique, chimie, sciences de la vie, environnement, informatique, sciences économiques et sociales, géographie, arts, philosophie, etc.) qui ont donné naissance à de nouveau concepts qui jalonnent l’histoire des civilisations occidentale, arabe, indienne, chinoise, etc.
La série Petits contes mathématiques raconte ces apports à l’histoire des sciences : - La racine carrée, pensée par un scribe babylonien vers 1700 avant JC - Le théorème de Thalès en Grèce au 5ème siècle avant JC - Les angles et Ptolémée au 2ème siècle à Alexandrie - Pour l’armée et le génie civil : GeoGebraTube.
