Question

The sum of the squares of the Eigen values of the matrix A = [ 2 1

0 2 ] is…….
​

Answer 1

Answer:

The eigenvalues of A2 are the squares of the eigenvalues of A. The sum of the eigenvalues of any matrix (with algebraic multiplicity) is the trace. So the sum of the squares of the eigenvalues of A (with algebraic multiplicity) is the trace of A2
