Description 1. Prove that operators i(d/dx) and d^2/dx^2 are Hermitian. 2. Operators A and B are defined by: A[itex]\psi[/itex](x)=[itex]\psi[/itex](x)+x B[itex]\psi[/itex](x)=[itex]d\psi/dx[/itex]+2[itex]\psi/dx[/itex](x) Check if they are linear. The attempt at a solution I noted the proof of the momentum operator '-ih/dx' being hermitian, should I just multiply all the terms involved in it by '-1/h'? I do not really know what should I do in the second exercise.
