Example from Schaum's Quantum Mechanics. Picture of the example is attached.
What I don't understand is part (c). What are those wavefunctions ##\mid \psi^{(0)}_{1,2} \rangle## and ##\mid \psi^{(0)}_{2,1} \rangle##? How do I find these wavefunctions, if the unperturbed wavefunction is ##\psi^{(0)}_{n_1,n_2}(x,y) = \frac{2}{L} \sin \left( \frac{\pi n_1 x}{L} \right) \sin \left( \frac{\pi n_2 y}{L} \right)##?
