Determinants are mathematical objects that are very useful in the analysis and solution of systems of linear equations. As shown by Cramer’s rule, a nonhomogeneous system of linear equations has a unique solution iff the determinant of the system’s matrix is nonzero (i.e., the matrix is nonsingular). In particular, we use the determinant to list several characterizations for matrix invertibility, and, as a corollary, give a method for using determinants to calculate eigenvalues. You should provide a proof of these results for your own benefit. The determinant of a matrix is a scalar value that is used in many matrix operations. The matrix must be square (equal number of columns and rows) to have a determinant. The notation for absolute value is used to indicate „the determinant of“, e.g. A means „the determinant of matrix A“ and a b means to c d take the determinant of the enclosed

For a rotation in R2 the determinant is 1 for a re ection, it is 1. In general, for any rotation the determinant is 1 as we can change the angle of rotation continuously to 0 forcing the determinant to be 1. The determinant depends continuously on the matrix. It can not jump from 1 to 1. Check the proof seminar in Unit 6. 11.12.

In linear algebra, a determinant is a special number that can be determined from a square matrix. The determinant of a matrix, say P is denoted det (P), |P| or det P. Determinants have some useful properties as they permit us to generate the same results with different and simpler entries (elements). There are 10 main properties of determinants: reflection property, all-zero property

In a triangular matrix, the determinant is equal to the product of the diagonal elements. The determinant of a matrix is zero if all the elements of the matrix are zero. Laplace’s Formula and the Adjugate Matrix Apart from these properties of determinants, there are some other properties, such as Reflection Property All-zero property
