WebSo if I'm taking the determinant of some kind of matrix, let's say, three, zero, one, two, something like this, to compute the determinant, you take these diagonal terms here, so you take three multiplied by that two, and then you subtract off the other diagonal, subtract off one multiplied by zero. And in this case, that evaluates to six. WebThe reduced row echelon form of the matrix is the identity matrix I 2, so its determinant is 1. The second-last step in the row reduction was a row replacement, so the second-final …
