Example 4: Finding the determinant of a 5 x 5 matrix
In this video I demonstrate how to find the determinant of a 5 x 5 matrix by using the cofactor expansion then for the remaining 3 x 3 matrix I demonstrate an alternative technique for finding the determinant. The technique shown for the 3 x 3 submatrix is often used in engineering applications and can only be applied to 3 x 3 matrices.
