Consider a quantum particle with potential energy V(x) which has a minimum and show that the energy eigenvalue E must exceed the minimum value of V(x) for every normalizable solution of the Schrodinger equation. (For simplicity, assume that the spacedependent part of the wavefunction u(x) is real.) What is the classical equivalent of this statement?
