Determinant and area of parallelogram
Web1. A determinant is linear in the elements of any row (or column) so that multiplying everything in that row by z multiplies the determinant by z, and the determinant with row v + w is the sum of the determinants otherwise identical with that row being v and that row being w. 2. It changes sign if two of its rows are interchanged ( an ... WebWe go from "y" equals five, to "y" is equal to negative seven, so this has length 12. We have five above the x-axis, and seven below the x-axis, adding up to 12. Or, you could count it: One, two, three, four, five, six, seven, eight, nine, ten, 11, 12. So, this is our base, and we could say that base is equal to 12.
