This paper describes the eccentricity, amplitude, phase shift, angular momentum, polarization, radial path, and orbital ...

THE question of the true geometric interpretation of the Mongian equation has been often considered by mathematicians. In the first place, we have the late Dr. Boole's statement that “here our powers ...

DR. TAYLOR'S “Geometry of Conics” is so well known, and has met with such acceptance—this is the seventh edition, revised—that we are not called upon to give a detailed account of it. Two additions, ...

We discuss some extremality issues concerning the circumradius, the inradius, and the condition number of a closed convex cone in Rn. The condition number refers to the ratio between the circumradius ...
