In mathematics, the determinant is a scalar value that is a function of the entries of a square matrix. It characterizes some properties of the matrix and the linear map represented by the matrix. In particular, the determinant is nonzero if and only if the matrix is invertible and the linear map represented by the matrix … See more The determinant of a 2 × 2 matrix $${\displaystyle {\begin{pmatrix}a&b\\c&d\end{pmatrix}}}$$ is denoted either by "det" or by vertical bars around the matrix, and is defined as See more If the matrix entries are real numbers, the matrix A can be used to represent two linear maps: one that maps the standard basis vectors … See more Characterization of the determinant The determinant can be characterized by the following three key properties. To state these, it is convenient to regard an See more Historically, determinants were used long before matrices: A determinant was originally defined as a property of a system of linear equations.
