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. WebChoose the row or column with the most 0 0 elements. If there are no 0 0 elements choose any row or column. Multiply every element in row 1 1 by its cofactor and add.
