- So why is it that he says there is 1 more constraint than free parameters instead of 2?
For the case of general potential V(x), what does it mean when he says that there are always one more constraint than free parameters? At each interval, ψ and ψ' must be continuous, so that is 2 constraints at each interval, and I understand that there are 2 parameters of the wavefunction in each interval between the leftmost and rightmost intervals. Getting rid of the rising exponential term at the extremes (x=±∞) so that the wavefunction doesn't blow up, that leaves us with one parameter at each extreme. So why is it that he says there is 1 more constraint than parameters instead of 2?
