\"abs%28matrix%283%2C3%2C1%2C-2%2C4%2Cu%2Cv%2Cw%2Cz%2Cy%2Cz%29%29\" or \"abs%28matrix%283%2C3%2C1%2C-2%2C4%2Cu%2Cv%2Cw%2C+x%2Cy%2Cz%29%29\" ?\r
\n" ); document.write( "\n" ); document.write( "Maybe one of the properties of determinants that you were taught is that if you interchange 2 rows (or two columns) the determinant changes sign.
\n" ); document.write( "So, if
