# Energy and momentum eigenfunctions

just a general and quick question because I'm making a formula sheet for my test tomorrow:

What is the energy eigenfunction for a free particle and what is the momentum eigenfunction for a particle in a box?

Why are you asking?!? If you're taking a QM class, surely you've covered these things in class and they are in your textbook!

i skipped QM and went into quantum theory so i never went over this. this isnt talked about in my book. all i need to know is the energy eigenfuction for a free particle please? Oh and momentum eigenvalues for a particle in a box?
