Homework Statement
a)For a general operator A, show that and i(A-A+) are hermitian?
b) If operators A and B are hermitian, show that the operator (A+B)^n is Hermitian.
Homework EquationsThe Attempt at a Solution
The first part I did,
(A+A+)+=(A++A)=(A+A+)...
if you use the dln(P)/dT = 1/P*dP/dT relation
P= -P (L/R * (1/T - 1/T0))
I understand you are trying to get me to work through the problem. The problem is my maths are wrong and need to be shown how to do it.
