... wave functions of exercise 1. Simplify them but don’t solve them (unless you really want to). Notice that exercise 2 results in 4 linear algebraic equations with 6 unknowns (the C’s and D’s). This means that there will still be 2 free parameters after solving the equations. As in the step function c ...
