Thanks @DominicMichaelis for pointing out the typo. –  Abhra Abir Kundu Mar 1 '13 at 13:45
@AbhraAbirKundu: of course you mean for square matrices as DM notes. Hint, try a 2x2, 3x3 and look for a pattern to generalize. –  Amzoti Mar 1 '13 at 13:48
Did you try anything? My first idea would be calculating for small $n$ and try to find a system –  Dominic Michaelis Mar 1 '13 at 13:49
Yes i did try for small $n$ like $n=2,3,4$ but couldn't find any pattern in those determinants. –  Abhra Abir Kundu Mar 1 '13 at 13:52

Thanks @pritam for the resource. –  Abhra Abir Kundu Mar 1 '13 at 13:56
@Abhra Abir Kundu: You are welcome, once you know the formula you can try to prove it by induction. –  pritam Mar 1 '13 at 14:06
