Problem:

Calculate the determinant:
				

Solution:

We will use row reduction to find a triangular matrix or co-factor matrices.




From the row reduction, we find the matrix is triangular.  The determinant
of a triangular matrix is the product of the elements on the diagonal.

		


We can check by co-factor of the first column of the original matrix:
