91Linear regression — Example of simple linear regression, which has one independent variable In statistics, linear regression is an approach to modeling the relationship between a scalar variable y and one or more explanatory variables denoted X. The case of one… …
92Riemann zeta function — ζ(s) in the complex plane. The color of a point s encodes the value of ζ(s): dark colors denote values close to zero and hue encodes the value s argument. The white spot at s = 1 is the pole of the zeta function; the black spots on the… …
93Inverse element — In abstract algebra, the idea of an inverse element generalises the concept of a negation, in relation to addition, and a reciprocal, in relation to multiplication. The intuition is of an element that can undo the effect of combination with… …
94Complex conjugate — Geometric representation of z and its conjugate in the complex plane In mathematics, complex conjugates are a pair of complex numbers, both having the same real part, but with imaginary parts of equal magni …
95List of abstract algebra topics — Abstract algebra is the subject area of mathematics that studies algebraic structures, such as groups, rings, fields, modules, vector spaces, and algebras. The phrase abstract algebra was coined at the turn of the 20th century to distinguish this …
96Affine cipher — Demonstration of an affine cipher using 17x + 5. First the letters are converted into numbers between 0 and 25, then 17x+5 is taken for each, then the results are reduced mod 26, then these are translated back into letters. The Affine cipher is a …
97Quantum number — Quantum numbers describe values of conserved numbers in the dynamics of the quantum system. They often describe specifically the energies of electrons in atoms, but other possibilities include angular momentum, spin etc.Since any quantum system… …
98Trigonometry in Galois fields — In mathematics, the theory of quadratic extensions of finite fields supports analogies with trigonometry.The main motivation to deal with a finite field trigonometry is the power of the discrete transforms, which play an important role in… …
99Idéal — Pour les articles homonymes, voir Idéal (homonymie). En mathématiques, et plus particulièrement en algèbre, un idéal est un sous ensemble remarquable d un anneau. Par certains égards, les idéaux s apparentent aux sous espaces vectoriels ce sont… …
100Logique Linéaire — La logique linéaire (LL), inventée par le logicien Jean Yves Girard en 1986, est un produit de la théorie de la démonstration moderne. Elle résulte d une analyse du comportement des preuves des logiques classique et intuitionniste au travers de… …
