Timeline of the development of main Linux distributions [1] This page provides general information about notable Linux distributions in the form of a categorized list. Distributions are organized into sections by the major distribution or package management system they are based on.
Viète. de Moivre. Euler. Fourier. v. t. e. In trigonometry, trigonometric identities are equalities that involve trigonometric functions and are true for every value of the occurring variables for which both sides of the equality are defined. Geometrically, these are identities involving certain functions of one or more angles.
Binomial distribution for p = 0.5with n and k as in Pascal's triangleThe probability that a ball in a Galton box with 8 layers (n = 8 ends up in the central bin (k = 4 is 70/256. In probability theory and statistics, the binomial distribution with parameters n and p is the discrete probability distribution of the number of successes in a sequence of n independent experiments, each asking a yes ...
