  2. Determinant - Wikipedia

    en.wikipedia.org/wiki/Determinant

    In mathematics, the determinant is a scalar-valued function of the entries of a square matrix.The determinant of a matrix A is commonly denoted det(A), det A, or | A |.Its value characterizes some properties of the matrix and the linear map represented, on a given basis, by the matrix.

    Instead, the determinant can be evaluated in () operations by forming the LU decomposition = (typically via Gaussian elimination or similar methods), in which case = and the determinants of the triangular matrices and are simply the products of their diagonal entries. (In practical applications of numerical linear algebra, however, explicit ...

  4. Cramer's rule - Wikipedia

    en.wikipedia.org/wiki/Cramer's_rule

    In the case of n equations in n unknowns, it requires computation of n + 1 determinants, while Gaussian elimination produces the result with the same computational complexity as the computation of a single determinant. [8] [9] [verification needed] Cramer's rule can also be numerically unstable even for 2×2 systems. [10]

    Determiner, also called determinative (abbreviated DET), is a term used in some models of grammatical description to describe a word or affix belonging to a class of noun modifiers. A determiner combines with a noun to express its reference .

    Even so, Zucman's 2018 list of top 10 havens also matched 9 of the top 10 havens in Hines' 2010 list, but with Ireland as the largest global haven. [65] These lists (Hines 2010, CORPNET 2017 and Zucman 2018), and others, which followed a purely quantitive approach, showed a firm consensus around the largest corporate tax havens.

    Prostitution is a type of sex work that involves engaging in sexual activity in exchange for payment. [1] [2] The definition of "sexual activity" varies, and is often defined as an activity requiring physical contact (e.g., sexual intercourse, non-penetrative sex, manual sex, oral sex, etc.) with the customer.
