Shankar's "Principals of Quantum Mechanics Hi, I study Shankar's "Principals of Quantum Mechanics". I didn't find Shankar's slutions of Quantum Mechanics. (for example, Exercise 5.2.1 - 5.2.2 - 5.2.3 - 5.4.6 so) Although the number of exercises is quite small, no answers are given. Do any of you know of a site where I might verify my results ? Thank you.
