    Graduate Why does the position expectation value vanish for odd wavefunctions?

    I have a question about expectation values in quantum mechanics. When calculating <x>=\int\Psi*x\Psi does x always make this functions odd? If \Psi is odd then \Psi* I would assume is odd as well and then <x> would be odd*odd*odd, if \Psi is even then I again assume it would be even*odd*even...
