1. The problem statement, all variables and given/known data

I have a question concerning this potential. For E < V0, I have the R and T coefficients, but there sum doesn't equal one, but you have six equations and six unknowns, so its easy to solve I guess.. I have gotten the same answers doing it different ways but can't seem to get R+T=1.

However, it is a lot easier case then solving the case for when E > V0 I have seven unknowns and six equations.

All these equations I have gotten from the continuity requirements. Could I be missing something else?

Could I at least change the interior wavefuntions into sine/cosine since the exponent forms since it's reduces unknowns when matching at zero?
