Practical Conic Sections: The Geometric Properties of Ellipses, Parabolas and Hyperbolas (2003) book download J. ELLIPSE The reflection property of parabolas is very important because it has so many practical uses. Conic Sections: Definition by focus - directrix property, eccentricity, definition of Parabola,. (That the definitions which follow are equivalent to those given above is not obvious – not at all! Introduction to light - optical medium - rectilinear propagation of light Reflection of light -. Consequently, one should master their “plane geometry” definitions as well. Simple Two Dimensional Geometry : Recall of Cartesian system of rectangular co ordinates in a plane, distance formula, area of a triangle, condition for the collinearity of three points and section formula, centroid and in centre of a triangle, locus and its equation, Conic Sections : Sections of cones, equations of conic sections (parabola, ellipse and hyperbola) in standard forms, condition for y = mx + c to be a tangent and point ( s ) of tangency. Laws of reflection - reflection at curved surfaces - image formation in the case of spherical. Ellipse, Hyperbola, Rectangular hyperbola. Mirrors - mirror formula (without derivation) - sign convention .. Properties of Binomial Co efficients. For an elegant proof, see the article on Dandelin's Spheres.) We will now look at each conic section in detail.
