1) Determine whether the following matrices are Hermitian (i.e. self-adjoint) or Unitary; justify your reponse by demonstrating either that A = A for the matrix if it is Hermitian or UUI if the matrix is unitary: i/√√20-i/√√2 -2 (a) 4-i 1 4+1-9 8i (b) 0 -9 -8i 3 10 i/√20 i/√2 i/2 1/2 1/2 1/2 3 4+5i 2-3i 8 1/2 (c) 1/2 1/2-1/2 4-5i 0 -9i 1+1 (d) i/2 -i/2-i/2 1/2 2+3i 9i 1 2-71 1/2 1/2 -1/2-1/2 8 1-i 2+71-5
