I have been given the following matrix and i am told there is a quick trick to getting the determinant:
0 1 2 3 4
0 0 2 3 4
0 0 0 3 4
0 0 0 0 4
5 4 3 2 1
I used my calculator and found out the answer is 120 which is 5!, but i am not sure what rule or reason the answer is 5!
Can ne one help?
0 1 2 3 4
0 0 2 3 4
0 0 0 3 4
0 0 0 0 4
5 4 3 2 1
