What are the energy eigenfunctions and eigenvalues for the one-dimensional box problem describ above if the end of the box are at -a/2 and a/2(adsbygoogle = window.adsbygoogle || []).push({});

I can find the solution of this problem Phi(x) = Asin kx + Bcos kx

and property of wavefunction is continuous at boundary

Phi(x=-a/2) = Phi(x=a/2)=0

but i don't understand to find k (wave number), please help me
