Determinant of Matrix Product - ProofWiki

WebThe determinant of a square matrix is a value determined by the elements of the matrix. In the case of a \(2 \times 2\) matrix, the determinant is calculated by … WebThe determinant can be evaluated using an expansion method involving minors and cofactors. Before we can use them, we need to define them. It is the product of the elements on the main diagonal minus the product of the elements off the main diagonal. In the case of a \(2 \times 2\) matrix, the specific formula for the determinant is

WebNov 30, 2016 · Cramer was the first to publish on the subject (1750). The theory of determinants is based on the work of A. Vandermonde, P. Laplace, A.L. Cauchy and C.G.J. Jacobi. The term "determinant" was first coined by C.F. Gauss (1801). The modern meaning was introduced by A. Cayley (1841). WebA determinant is a property of a square matrix. The value of the determinant has many implications for the matrix. A determinant of 0 implies that the matrix is singular, and thus not invertible. A system of linear equations can be solved by creating a matrix out of the coefficients and taking the determinant; this method is called Cramer's ...
