91Negative number — This thermometer is indicating a slightly negative …
92Atan2 — In computing, atan2 is a two argument function that makes it easy to find the angle round the origin of a point. When given the coordinates ( x , y ) the angle is atan2( y , x ). It is implemented in many different programming languages. The… …
93Outline of discrete mathematics — The following outline is presented as an overview of and topical guide to discrete mathematics: Discrete mathematics – study of mathematical structures that are fundamentally discrete rather than continuous. In contrast to real numbers that have… …
94List of basic discrete mathematics topics — Discrete mathematics, also called finite mathematics, is the study of mathematical structures that are fundamentally , in the sense of not supporting or requiring the notion of continuity. Most, if not all, of the objects studied in finite… …
95Potential game — A game in game theory is considered a potential game if the incentive of all players to change their strategy can be expressed in one global function, the potential function. The concept was proposed by Dov Monderer and Lloyd Shapley. Games can… …
96Natural language programming — Not to be confused with Neurolinguistic programming. Natural language programming NLP is an ontology assisted way of programming in terms of natural language sentences, e.g. English. A structured document with Content, sections and subsections… …
97Marcinkiewicz interpolation theorem — In mathematics, the Marcinkiewicz interpolation theorem, discovered by Józef Marcinkiewicz (1939), is a result bounding the norms of non linear operators acting on Lp spaces. Marcinkiewicz theorem is similar to the Riesz–Thorin theorem about …
98Tractrix — (from the Latin verb trahere pull, drag ), or tractrice, is the curve along which a small object moves, under the influence of friction, when pulled on a horizontal plane by a piece of thread and a puller that moves at a right angle to the… …
99Weak derivative — In mathematics, a weak derivative is a generalization of the concept of the derivative of a function ( strong derivative ) for functions not assumed differentiable, but only integrable, i.e. to lie in the Lebesgue space L^1( [a,b] ). See… …
100Arg (mathematics) — In mathematics the arg function is a logical function that extracts the angular component of a complex number or function.An alternative definition is available at Complex argument (continued fraction). The essential difference is the treatment… …
