For a 2×2 matrix the determinant is ad - bc For a 3×3 matrix multiply a by the determinant of the 2×2 matrix that is not in a 's row or column, likewise for b and c, but remember that b has a negative sign! 2013-05-27 · If a matrix A = [2 x 2] has 2 eigenvalues, then it is diagonalizable: A = PDP^{-1} where P are 2 x 2 matrices whose columns are the eigenvectors that are listed to be correspondent to the eigenvalues listed in the diagonal matrix D. That is, D = diag(eig(A)) det(A) = det(PDP^{-1}) = det(P)det(D)det(P^{1}) by elementary determinant properties Each determinant of a 2 × 2 matrix in this equation is called a minor of the matrix A. This procedure can be extended to give a recursive definition for the determinant of an n × n matrix, known as Laplace expansion. Determinants occur throughout mathematics.
