lt;br /gt; 1PC 30402 conic curve model parabola hyperbola ellipse analytic geometry high school mathematics teaching aids teaching instrumentslt;br /gt;

lt;br /gt;30402 conic curve model instructions for uselt;br /gt;

lt;br /gt;A use: .lt;br /gt;
lt;br /gt;Secondary school mathematics in algebra, stereometry, analytic geometry and other disciplines, the circle ellipse, parabola, hyperbola occupies a very important position. In order to understand more deeply the formation of the conic curve and its geometric meaning, we designed this set of conic curve model, which consists of two cones that can be split.lt;br /gt;

lt;br /gt;II. Usage.lt;br /gt;
lt;br /gt;1. Demonstrate the circle and ellipse. When a positive cone is truncated by a plane, its truncated opening is a circle or an ellipse.lt;br /gt;
lt;br /gt;2, demonstration of parabola, when a positive cone by a parallel to the parent line, its intercept opening for the parabola.lt;br /gt;
lt;br /gt;3?Demonstrate the parabola, when a cone is truncated by a plane parallel to the axis, its intercept is a hyperbola (a)).
It can be proved that the equation of the intercept is a circle, ellipse, parabola, hyperbola (for detailed proof, please refer to "Geometry Dictionary" Analytic Geometry).lt;br /gt;

lt;br /gt;Caution: 1.lt;br /gt;
lt;br /gt;1. Do not press the model hard to avoid damage and deformation.lt;br /gt;
lt;br /gt;2. Avoid collision with hard objects.lt;br /gt;
