If no line of the cone is parallel to the plane, the intersection is a closed curve, called an ellipse. If one line of the cone is parallel to the plane, the intersection is an open curve whose two ends are asymptotically parallel.

Publishing platform for digital magazines, interactive publications and online catalogs. His elements is one of the most influential works in the history of mathematics, serving as the main textbook for teaching. We make a deep study of the vertex, local extrema, asymptotes, the latus rectum and the graph of the resulting. A geometrical treatise on conic sections, with numerous examples. Apollonius of perga greatly contributed to geometry, specifically in the area of conics. Scribd is the worlds largest social reading and publishing site. Now given the two focus of the ellipse b 1 and b 2 we can give an alternative geometric description, in the following way. Conic sections are graceful curves that can be defined in several ways and constructed by a wide variety of means. An ellipse is the set of points such that the sum of the distances from any point on the ellipse to b 1. Alternatively, an ellipse is the set of all points in the plane whose distances from a fixed point in the plane bears a constant ratio, less than, to their distance from a fixed line in the plane. Conicas y lugares geometricos problemas resueltos ejercicio n. For the use of schools and students in the universities.
A conic is a twodimensional gure created by the intersection of a plane and a right circular cone. The debris is as small as sand and can pass through the body without discomfort. Convert documents to beautiful publications and share them worldwide. The four conics well explore in this text are parabolas, ellipses, circles, and hyperbolas. Sep 01, 2008 the file size of this svg image may be abnormally large because most or all of its text has been converted to paths rather than using the more conventional element. Most importantly, when a plane intersects a cone, the outline of a conic section results.
