![]() ![]() I know a lot of people learned quantum mechanics from this textbook. Sure that proofs exist for each of them, then I could continue trying to use Griffiths. If there was a finite list of these identities that I was allowed to use in the exercises, and I was I found these in other people's solutions. In fact, I don't even know if he used these identities in his solutions. But Griffiths hasn't said these willīe explained later. I understand that in learning a new subject you sometimes have to take some things on faithĪt the beginning, knowing they will be explained later. Want and stick it in your solution so you get the answer you need. I don't see any point in trying to doing the exercises if you can just make up anything you Griffiths never mentioned these identities, much less justified them. That people have provided online and they are making assumptions like these: He states that the wave function #\psi# approaches 0 as x approaches infinity to make normalization work.īut then I can't solve the problems in the book so I peak at some of the solutions ![]() I am trying to use Griffiths Introduction to Quantum Mechanics. ![]() Summary:: The problem solutions contain a lot of unjustified steps, making them pointless. ![]()
