Inverting a 3x3 matrix using determinants Part 2: Adjugate matrix

Adjugate Matrix Overview, Steps & Example

SOLVED: Compute the adjugate of the given matrix, and then use the Inverse Formula to give the inverse of the matrixThe adjugate of the given matrix is adj A = (Type an integer or simplified fraction for each matrix element ) The inverse of the given matrix is A -1 = (Type an integer or simplified fraction for each matrix element )

SOLVED:Definition. The classical adjoint of a square matrix A is the transpose of the matrix whose i j -entry is the i j -cofactor of A Find the classical adjoint of each of the following matrices. (a) ( A11 A12 A21 A22 ) (b) ( 4 0 0 0 4 0 0 0 4 ) (c)( -4 0 0 0 2 0 0 0 5 ) (d) ( 3 6 7 0 4 8 0 0 5 ) (e)( 1-i 0 0 4 3 i 0 2 i 1+4
