âVerticesâ are the points on the two arms which are closest; whereas the line segment which connects the arms is called the âmajor axis.â. In a parabola, the two arms of the curve, also called branches, become parallel to each other. In a hyperbola, the two arms or curves do not become parallel. A hyperbolaâs center is the midpoint of the major axis. Hyperbola is given by the equation XY=1. When the difference of distances between a set of points present in a plane to two fixed foci or points is a positive constant, it is called a hyperbola.

Almost all Norman surnames were derived from a place name, and Mallory is no exception. There were at least two villages in France at that time called Meillorie (possible spelling).

Meillorie is from the ancient Latin root 'molere' (mele-), meaning to crush or grind with a turning motion, a mill.
