Parabolic Antenna : Mathematical Etudes A satellite's orbit is called geostationary if as the Earth turns, the satellite stays above the same point of our planet's surface. Such orbits are often used in positioning and communication systems. he satellite you see on the picture is the symbol of the Russian space program. This is SOUZ-TM. And this is how the beginning of the main Russian television news program "Vremia" looked like some time ago. In our movie we'll see how signal transduction works, say, in modern satellite television. Draw a line and call it a directrix. If we direct a beam parallel to the parabola's symmetry axis they'll meet at it's focus. The converse is also true. Rotating a parabola around it's symmetry axis one gets a second-order surface of rotation - a paraboloid. Exactly this property is used in satellite parabolic antennas.

Writing Prompts 2 plus 2: The Home of Mathematically Correct Mathematics Grade 7 [2011] Core Course Description In Grade 7, instructional time should focus on four critical areas: (1) developing understanding of and applying proportional relationships; (2) developing understanding of operations with rational numbers and working with expressions and linear equations; (3) solving problems involving scale drawings and informal geometric constructions, and working with two- and three-dimensional shapes to solve problems involving area, surface area, and volume; and (4) drawing inferences about populations based on samples. (1) Students extend their understanding of ratios and develop understanding of proportionality to solve single- and multi-step problems. Grade 7 Overview Mathematical Practices Make sense of problems and persevere in solving them. Ratios and Proportional Relationships Analyze proportional relationships and use them to solve real-world and mathematical problems. Expressions and Equations Use properties of operations to generate equivalent expressions. 1. 1. 1.

Art with Mrs. Nguyen: Radial Paper Relief Sculptures (4th/5th) For this lesson we began by taking about what symmetry is and the difference between linear symmetry (1 line of symmetry) and radial symmetry (more than 1 line of symmetry). Then we talked about what a sculpture is (a piece of artwork you can see from all sides - it is 3-dimensional) and what a relief "sculpture" is (a piece of artwork that has depth on the surface but is not meant to be seen from all sides). Once students understood the principles behind radial symmetry and sculpture we began creating our very own radial paper relief sculptures! Students started by folding a piece of 12"x12" black construction paper diagonally both ways and vertical and horizontally (to create an 'X' crease and a '+' crease). Before having students begin folding their colored paper (each piece was cut to 3" x 3") to fill the inside of their design, I demonstrated 4 folds to them to get them started. My kids absolutely LOVED this project!

Free truetype fonts - downloadable fonts for windows and mac at fonts101.com BA - Balanced Assessment in Mathematics Math Vocabulary These comprehensive math vocabulary lists are based on the Common Core State Math Standards and are organized by grade level. The lists are also organized by the key K12 Common Core math content categories (geometry, measurement & data, etc.). These hundreds of academic vocabulary lists, comprised of thousands of key math terms, can be used with all twenty-five of VocabularySpellingCity's learning activities. The Math Common Core State Standards provide clear goals defining what students should understand and be able to do at every grade level. On every math page, there is a "standards overview table" summarizing the Common Core Standards' math learning goals and skills for that grade and content area. The Common Core State Standards for Mathematical Practice establish eight main math skills that K12 educators should develop in their students: Make sense of problems and persevere in solving them. Math is omnipresent in our everyday world.

Interactive angles teaching tool acute,obtuse,measure with protractor This activity allows manipulation and investigation of various types of angles. It can be used at a variety of different grade levels. At its most basic for teaching about types of angles, acute, obtuse or reflex. For more advanced use to create angle problems in which the missing letter angle values have to be found. The controls The mode control is used to it selects the type of angle problem. In all the modes individual angles can be shown or hidden for example click the angle (a). The handles at the end of each line can be clicked and dragged to change the angle. Mode 'one' Identifying angle types. The initial mode is unique in that there is only one angle. Complementary Angles mode In this mode a complementary angle is shown, complementary angles add up to 90° Initially the 90° is split by just one line but this can be changed by selecting a different number of lines. Supplementary Angles mode Supplementary angles are angles that add up to 180°. Angles at a point mode Angles Glossary

La droite dans le plan : équation paramétrique – Clipedia - La science et moi La droite dans le plan : équation paramétrique Publiée le 28 mai 2016 Comment fait-on avec un ordinateur pour tracer une droite (à l’écran ou à l’aide d’une imprimante) ? C’est la question qui nous sert de motivation pour introduire l’équation de la droite sous forme paramétrique. Nous commençons par le problème de la droite passant par deux points donnés, a et b. Nous terminons la séquence avec la détermination de l’équation d’une droite passant par un point a et dont la direction est fixée. Cette séquence constitue une introduction efficace à la notion d’équation paramétrique, en particulier, pour préparer à l’équation paramétrique de la droite dans l’espace (3D) et l’équation paramétrique du plan.
