    Do not solve the problem just look at the picture.

    Well its the end of the semester and I found out that I had only one of the required books for my undergraduate course.

    Anyways back to the question. As you can see in the photo what I would like to know is what
    ψ_0(x)= <x|0>. stands for?

    I haven't seen examples of how to use it or anything. I do know that it can be broken up and something can be placed in the center <x|?|0>.

    what i don't know is what that x is or why there's a zero on the other side. What does it mean I would like to have examples if possible.

    The [itex]\mid 0 \rangle [/itex]indicates the ground state. The [itex]\langle x\mid [/itex] is the bra for "x" basis state, which is the state associated with the position x.
