If you use pencil, do not erase anything. If there are erasures, you get zero points. ˆ f ( x ) is an eigenfunction of the Hermitian operator Q: Q f = q f . ˆ ˆ The expectation value for this state is: f Qf = Qf f This can be written as: qf f = f qf q* f f = q f f 1. Is this last equation satisfied if f f = 0 ? YES NO 2. Is f ( x ) = 0 a valid eigenfunction? YES NO 3. Does this mean that q* = q ? YES NO ...
