61Digamma function — For Barnes s gamma function of 2 variables, see double gamma function. Digamma function ψ(s) in the complex plane. The color of a point s encodes the value of ψ(s). Strong colors denote values close to zero and hue encodes the value s argument …
62Mertens function — to n=10,000 Mertens function to n=10,000,000 In …
63Bump function — In mathematics, a bump function is a function f: {Bbb R}^n o {Bbb R} on a Euclidean space {Bbb R}^n which is both smooth (in the sense of having continuous derivatives of all orders) and compactly supported. The space of all bump functions on… …
64Thomae's function — If you are having difficulty understanding this article, you might wish to learn more about algebra, functions, and mathematical limits. Thomae s function, also known as the popcorn function, the raindrop function, the ruler function or the… …
65Riemann-Siegel theta function — In mathematics, the Riemann Siegel theta function is defined in terms of the Gamma function as: heta(t) = arg left(Gammaleft(frac{2it+1}{4} ight) ight) frac{log pi}{2} tfor real values of t. Here the argument is chosen in such a way that a… …
66Divisor summatory function — The summatory function, with leading terms removed, for x < 104 …
67Graph of a function — In mathematics, the graph of a function f is the collection of all ordered pairs ( x , f ( x )). In particular, if x is a real number, graph means the graphical representation of this collection, in the form of a curve on a Cartesian plane,… …
68Open and closed systems in social science — Ludwig Bertalanffy describes two types of systems: open systems and closed systems. The open systems are systems that allow interactions between its internal elements and the environment. An open system is defined as a “system in exchange of… …
69Quasi-algebraically closed field — In mathematics, a field F is called quasi algebraically closed (or C1) if for every non constant homogeneous polynomial P over F has a non trivial zero provided the number of its variables is more than its degree. In other words, if P is a non… …
70Double exponential function — A double exponential function (red curve) compared to a single exponential function (blue curve). A double exponential function is a constant raised to the power of an exponential function. The general formula is , which grows much more quickly… …
