The determiners form a closed lexical category in English. [2] The syntactic role characteristically performed by determiners is known as the determinative function (see § Terminology). [3] A determinative combines with a noun (or, more formally, a nominal; see English nouns § Internal structure) to form a noun phrase (NP).
a; a few; a little; all; an; another; any; anybody; anyone; anything; anywhere; both; certain (also adjective) each; either; enough; every; everybody; everyone ...
In English, for example, the words my, your etc. are used without articles and so can be regarded as possessive determiners whereas their Italian equivalents mio etc. are used together with articles and so may be better classed as adjectives. [4] Not all languages can be said to have a lexically distinct class of determiners.
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.
The Jacobian determinant is sometimes simply referred to as "the Jacobian". The Jacobian determinant at a given point gives important information about the behavior of f near that point. For instance, the continuously differentiable function f is invertible near a point p ∈ R n if the Jacobian determinant at p is non-zero.
Possessive determiners, as used in English and some other languages, imply the definite article.For example, my car implies the car of mine. (However, "This is the car I have" implies that it is the only car you have, whereas "This is my car" does not imply that to the same extent.

The proof for Cramer's rule uses the following properties of the determinants: linearity with respect to any given column and the fact that the determinant is zero whenever two columns are equal, which is implied by the property that the sign of the determinant flips if you switch two columns.
