I love to program and crosscompile baremetal C programs for ARM based microcontrollers, I love physics and i love writing science documents/books in LaTeX. It amazes me how physics is connecting all science and is helping mathematics to evolve. In order for science profession to comunicate on a high level i advise everyone to use Linux, LaTeX and a good vector imaging program like Inkscape.

Wouldnt i get the energy of this state if i used hamiltonian on the wavefunction???

comment Finite potential well problem - calculating the ground state
Thank zou for the info about normalization. Concerning the numerical value - the particle is an electron so just use its mass, but i really forgot to give the depth of a potential well which is $20eV$. Do you use mathematica?

Thank you for pointing this out. I voted up your anwser.

I recalculated them and got a bit different than yours are. I got $\psi(x) = \sqrt{\frac{2}{L}}\sin\left(\frac{2n\pi x}{L}\right)$ and $\psi(x) = \sqrt{\frac{2}{L}}\cos\left(\frac{(2n-1)\pi x}{L}\right)$. Oh bummer...

comment Should normalisation factor in a QM always be positive?
Thanks for adding an extended anwser. My two equations for an infinite potential well that i wrote above for the interval $-d/2<x<d/2$ ($d\equiv L$)are clearly wrong too (if i solve them for $x=\pm d/2$ i don't get zero). Could you participate in my other topic to where i derived them to help me clear this mess in my head now..
