depending on what bits of physics you're interested in, i would (no matter which topic) get Duffin for electromagnetism, and mechanics, i don't know if its basic mechanics, pretty much anything will do, have a look at each book and see if it seems understandable. that said however, single...

oh yeah of course, they aren't normalizable. i completely spaced on the fact that this is in a box. obviously we need bound states... sorry to the op.

i think the idea here is this: you have and incident wave, and reflected wave and a transmitted wave. split the problem into two parts. in region (1) (ie before the potential) the wave could be of the form q(x) = Aexp(ikx) + bexp(-ikx) (+ikx for he incident, -ikx for reflected). and in region...
