A.) prove that the anti-commutator of any two operators, {a, b} = ab+ ba , is hermitian if the operators are hermitian.
b.) prove that the commutator of any two hermitian operators is anti-hermitian ( anti-hermitian satisfies if \hat{c} = - \hat{c}^\dagger , and hermitian satisfies if \hat{c} = \hat{c}^\dagger ).
