Eisco GP00011 Garage Physics Trigonometry Exploration Puzzle Set - This block kit puts trigonometry directly in your hands. Sine, Cosine, Tangent and the other trig functions take physical form and become real. Students can explore with their own hands the definition of the radian unit of angular measurement and even come up with their own approximation of Pi. The material is high quality precision-cut Birch verner pure bond plywood with no assembly required. The included pedagogy walks students through the definition of all six trigonometric functions and uses the properties of similar triangles and the Pythagorean theorem to help students establish the critical relationships between them. Also included are 1 radian and 2 radian circular sectors. Kit includes * Step-by-step educational guide * Unit circle * Three 30-60-90 triangles * Two 45-45-90 triangles * Two circular sectors * Kepler's triangle. https://elecena.pl/product/27244075/eisco-gp00011-garage-physics-trigonometry-exploration-puzzle-set 2024-11-12 https://elecena.pl/product/27244075/eisco-gp00011-garage-physics-trigonometry-exploration-puzzle-set 2024-12-21 https://elecena.pl/product/27244075/eisco-gp00011-garage-physics-trigonometry-exploration-puzzle-set 2025-01-07 https://elecena.pl/product/27244075/eisco-gp00011-garage-physics-trigonometry-exploration-puzzle-set 2025-02-03 https://elecena.pl/product/27244075/eisco-gp00011-garage-physics-trigonometry-exploration-puzzle-set 2025-04-07 https://elecena.pl/product/27244075/eisco-gp00011-garage-physics-trigonometry-exploration-puzzle-set 2025-05-25 https://elecena.pl/product/27244075/eisco-gp00011-garage-physics-trigonometry-exploration-puzzle-set 2025-08-11
