2. Relevant equations

[tex]H|\psi > = E_n |\psi >[/tex]

3. The attempt at a solution

About part 1 of the question: I can find the eigenfunctions of psi_1 by comparing coefficients with the well known eigenfunctions of the Hamiltonian in an infinite well, using trigonometric identities, but is there any simple way to find the eigenfunctions of psi_2, without actually solving the SchrÃ¶dinger equation?

Thanks :)
