Determinant as area

WebDeterminants originate as applications of vector geometry: the determinate of a 2x2 matrix is the area of a parallelogram with line one and line two being the vectors of its lower left hand sides. (Actually, the absolute value of the determinate is equal to the area.) Extra points if you can figure out why. (hint: to rotate a vector (a,b) by 90 ... WebThis map transforms the rectangular mesh cell with width $\Delta u$ and height $\Delta v$ into a parallelogram, and the area of this parallelogram is $\Delta u\Delta v \det(J(u,v))$, i.e., per the above discussion the area of the rectangular cell is scaled by the Jacobian determinant of $\phi$ evaluated at a vertex of the cell.
