Det meaning in math
Did you know?
WebFormally, the determinant is a function \text {det} det from the set of square matrices to the set of real numbers, that satisfies 3 important properties: \text {det} (I) = 1 det(I) = 1. \text {det} det is linear in the rows of the matrix. \det (M)=0 det(M) = 0. The second condition is by far the most important. Web$\begingroup$ I mean, like in a homogeneous system of equations,if det(A)=0,then the system has infinite number of solutions else if det(A) is not zero then it has one a unique,but trivial solution.I want to know what happens for the case of non-homogeneous equations.Thanks. $\endgroup$ –
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 to the rows of A, and one that maps them to the columns of A. In either case, the images of the basis vectors form a See more Eigenvalues and characteristic polynomial The determinant is closely related to two other central concepts in linear algebra, the eigenvalues and the characteristic polynomial of a matrix.
