Just read the "how to ask for help" sticky.
My attempt at a solution involved subbing y = -x. Obtaining a solution, then trying to normalise it. However I don't get anywhere really, and my line of argument through my current page of working reads unconvincing (I'm just guessing).
Cheers
Hopefully this is in the correct section.
Struggling with this question though I don't think it should be particularly difficult:
Show that if V(x) = V(-x) normalised solutions to the time-independent Schrodinger equation have definite parity - that is, u(x) = +-u(-x)
(+- means plus or...
