Hi..I have a very basic query...while solving a determinant, when we exchange/swap 2 rows we need to add a negative sign to the determinant. However, when we are trying to reduce a matrix to a row echelon form, when we swap 2 rows..do we need to add a negatice sign here as well??? Well..from what I've read...theres no need to..But I'm not sure why..can anyone throw some more light on this??..thanks(adsbygoogle = window.adsbygoogle || []).push({});
