Homework Help: Quantum Problems

  1. Apr 12, 2010 #1
    I've attached my notes for this course that I'm taking.
    I have a couple of questions about the material at the bottom of p15/top of p16.

    Where does eqn 2.49 come from? Why is there an [itex]|x,t \rangle[/itex] on one side and a [itex]| x \rangle[/itex] on the other?

    Where does eqn 2.50 come from? It's a rearranging of the line above essentially. But when i left multiply [itex]\hat{H}(t) | x,t \rangle = - i \hbar \frac{\partial}{\partial t} | x,t \rangle[/itex] by [itex]\langle \psi |[/itex], i don't get the right result since i don't think we can move the psi ket through either the hamiltonian operator or the time derivative, can we?
