Extrema (mathematics)
In mathematical analysis, the maxima and minima (the respective plurals of maximum and minimum) of a function (mathematics), function, known collectively as extrema (the plural of extremum), are the largest and smallest value of the function, either within a given Interval (mathematics), range (the ''local'' or ''relative'' extrema), or on the entire domain of a function, domain (the ''global'' or ''absolute'' extrema). Pierre de Fermat was one of the first mathematicians to propose a general technique, adequality, for finding the maxima and minima of functions. As defined in set theory, the maximum and minimum of a set (mathematics), set are the greatest and least elements in the set, respectively. Unbounded infinite sets, such as the set of real numbers, have no minimum or maximum. Definition A real-valued Function (mathematics), function ''f'' defined on a Domain of a function, domain ''X'' has a global (or absolute) maximum point at ''x''∗, if for all ''x'' in ''X''. Sim ...

In toe-walking ungulates, the term typically refers to the hoofed portion of the foot. ** Paw, a furry, padded foot with claws, common in many quadruped animals * Appendage, any external body part that protrudes outwards from an organism's core, such as a limb, tail, ear, nose, horn/antler, external genitalia, antenna, tusk/ mouthpart or raptorial The term ''raptorial'' implies much the same as ''predatory'' but most often refers to modifications of an arthropod's foreleg that make it function for the grasping of prey whil ...
