In polar coordinates, this figure can be described by the equation r times the term one plus cosine theta equals the semilatus rectum.
In polar coordinates, this figure can be described by the equation r times the term one plus cosine theta equals the semilatus rectum. This is the shape of an orbit for an object at the moment it reaches, but does not exceed, the escape velocity. Because of the ability of this shape to focus light on a point, it is the proposed shape for Archimedes "death ray". For 10 points, identify this conic section with an eccentricity of exactly one, defined as the set of points on a plane equidistant from a line called the directrix and a point called a focus which is exemplified by the graph of the equation y equals x squared.
