The Hamiltonian of a two-level system is given by H =hoo,. At time 1 =0 the system is in the eigenstate of o, having the largest eigenvalue. The expectation values (o,)(t).(0.)(+) and (o.)() (where o, are Pauli matrices) are respectively (a) sin at ,0, and cos (b) cos sin and 0 2 ot and sin 2 ,0 and sin 2 (c) 0,cos (d) -cos
