Each term is the product of an entry, a sign, and the minor for the entry. The signs look like this: A minor is the 2×2 determinant formed by deleting the row and column for the entry. For example, this is the minor for the middle entry: Here is the expansion along the ...
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 is an isomorphism. The determinant of a product of matrices is the product of their determinants (the preceding property is a corollary of this one). The determinan… Web18 Jan 2024 · Chemical determinands.
