1. The problem statement, all variables and given/known data V(x) = 0 for x < 0; V0 for 0 < x < a; 0 for x > a Particle of mass m E=V0 Asks for general solution and transmission coefficient. 2. Relevant equations Time-Independent Schrodinger Equation 3. The attempt at a solution I've found region I (the left region where x <0) to be Aeikx+Be-ikx. Middle region to be C+Dx (not sure where this comes from but I read that this is the solution to the middle region when E=V0 so any help with this is appreciated). Right region where x > a to be Feikx+Ge-ikx. My textbook has the right region in an example as just Feikx. It goes through the explanation of limits mattering as x-> infinity or -infinity. I understand this for when E<V0, but the case seems completely different when E=V0. Any help is appreciated. Thanks.
