Its definition is unfortunately not very intuitive.

In a determinant each element in any row (or column) consists of the sum of two terms, then the determinant can be expressed as sum of two determinants of same order.Let $\mathbf A = \sqbrk a_n$ and $\mathbf B = \sqbrk b_n$ be a square matrices of order $n$. The determinant of a square matrix is a number that provides a lot of useful information about the matrix.Determinant of diagonal matrix, triangular matrix (upper triangular or lower triangular matrix) is product of element of the principle diagonal.Determinant of Inverse of matrix can be defined as | | =.Let A and B be two matrix, then det(AB) = det(A)*det(B).If two rows (or columns) of a determinant are identical the value of the determinant is zero.Therefore, If A be an n-rowed square matrix and K be any scalar. If all elements of a row (or column) of a determinant are multiplied by some scalar number k, the value of the new determinant is k times of the given determinant.For example 2x2 matrices represent transformations in 2. If A is a triangular matrix, then the detA is the product of the main diagonal entries. The determinant of a matrix is the total scaling factor of the transformation that it represents. For any nxn matrices A and B, the det (AB) (detA) (detB) 3. If any two row (or two column) of a determinant are interchanged the value of the determinant is multiplied by -1. A square matrix is invertible if and only if the determinant of A does not equal zero. Field Rank of a matrix Determinant after elementary row operation A field is an integral domain Full-rank square matrix in RREF is the identity matrix.Therefore, det(A) = det( ), here is transpose of matrix A. determinant is a generic function that returns separately the modulus of the determinant, optionally on the. It calculated from the diagonal elements of a square matrix. If rows and columns are interchanged then value of determinant remains same (value does not change). det calculates the determinant of a matrix. Determinant is a very useful value in linear algebra.Determinant of a Identity matrix ( ) is 1.Determinants also have wide applications in engineering, science, economics and social science as well. Determinants are mathematical objects that are very useful in the analysis and solution of systems of linear equations. That is, the value of a determinant equals the sum of the products of the entries in anyone row or column and their respective cofactors. If all the elements of a row (or column) are zeros, then the value of the determinant is zero.
