Conic curve
Conic section, also known as conical cut, conical section, quadratic plane curve, is the mathematical, geometric geometry through the tangent cone (strictly for a positive cone and a plane tangent tangent) to get the curve , Including circles, ellipses, parabolic, hyperbolic, and some degradation types. The conic curve was named and studied at about 200 BC, and its discoverer was the ancient Greek mathematician Apollonios, when Apollonas had made a systematic study of their nature The The most widely used conic curve is defined as (elliptic, parabolic, unified definition of hyperbolic): the ratio of the distance from a point to a point (focus) to its distance to a straight line (line) is constant (eccentricity e) The set of points is a conic curve. For o \u0026 lt; e \u0026 lt; 1, an ellipse is obtained, a parabola is obtained for e = 1, and a hyperbola is obtained for e \u0026 gt; 1. ...
