Objects for which this value is zero are called singular, as they lack inverses.
The rule of Sarrus is an aid for calculating this quantity in one special case, wherein it corresponds to the volume of a parallelepiped. A change-of-variables in an integral requires multiplying by the Jacobian one. Objects for which this value is zero are called singular, as they lack inverses. For 10 points, name this operation which, in one case, takes the difference between the product of the main and off diagonal elements of a matrix.
