Step 1
To find the determinant of the matrix by the pivotal element method, use the following steps.
- Choose the element 1 in the matrix as a pivotal element and cross out the row and column through the pivotal element.
- Suppose is a pivotal element of an matrix A. Then, the determinant of the matrix A is calculated as follows., where B is a matrix of order which is obtained by subtracting the product of elements in pivotal row and column from the remaining entries of the matrix.
