A particle of mass m is confined to a circle of radius a, but is otherwise free. A perturbing potential H=Asinφcosφ is applied, where φ is the angular position on the circle. Find the correct unperturbed wave functions for the two lowest states of this system and calculate their first order perturbed energies.
