WebOne way to calculate the determinant of a 3 × 3 matrix is through the use of the Laplace formula. Both the Laplace formula and the Leibniz formula can be represented mathematically, but involve the use of notations and concepts that won't be discussed here. WebNow, A 3 is just the same only that x, y, z ∈ A. Since A is a finite set in your case, you just have a finite number of choices, and you can list them all. For A = { 0, a } you can decide for each of x, y, z if it is a or 0; for A = { a } you have no real choice at all but must always …
