Mar 15, 2017 at 13:57 | comment | added | ZeroTheHero | @garyp the higher wave vectors would come out "naturally" by enforcing the conditions at the boundaries, which could have multiple solutions. | |
Mar 15, 2017 at 13:51 | comment | added | garyp | Your "general solution" is not. You don't allow for higher wave vectors. Also, if your solution is instead a "particular" solution for a particular eigenvalue, you should be able to find that eigenvalue from Schrodinger's eqn. Try to find the eigenvalue for your solution and see what you get. | |

Mar 15, 2017 at 13:39 | comment | added | ZeroTheHero | If your boundaries are at $x=\pm L/2$, why do you use a condition like $\psi(0)=0$, which is clearly NOT correct? Have you considered working backwards: starting from the solution between $x=0$ and $x=L$ and making the substitution $x\to x+L/2$ so as to shift the potential between $-L/2$ and $L/2$? | |
Mar 15, 2017 at 13:39 | comment | added | Michael Seifert | The third unknown is usually determined by requiring $\psi(x)$ be normalized, i.e., $\int |\psi(x)|^2 dx = 1$. | |

fixed minor math typesetting and minor grammar.
