Compute the determinant of the matrix [ [1,0,0], [2,1,0], [3,4,1] ].

For a triangular matrix, the determinant is simply the product of the diagonal entries. This matrix has zeros above the main diagonal, so it’s lower triangular. The diagonal entries are 1, 1, and 1, and their product is 1. So the determinant is 1.
