WebDeterminant of Inverse Matrix - Key takeaways. Determinant of a matrix: For a square matrix of order 2 - determinant is equal to the subtraction of the product of off-diagonal elements from the product of the main diagonal elements.For a square matrix of order 3 or higher - determinant is equal to the sum of the product of the elements of a row or … WebThe determinant of a matrix can be either positive, negative, or zero. The determinant of matrix is used in Cramer's rule which is used to solve the system of equations. Also, it is used to find the inverse of a matrix. If the determinant of a matrix is not equal to 0, then it is an invertible matrix as we can find its inverse.
