Hi, I have to derive the ket |[tex]\phi[/tex]> that corresponds to the wavefunction [tex]\phi[/tex](x). I've done this out with the information given to point where I've gotten:

|[tex]\phi[/tex]> = [tex]\alpha[/tex]|0> + [tex]\beta[/tex]|2>

How can I go further in evaluating this?

[tex] |\phi \rangle ~=~ \alpha |0 \rangle ~+~ \beta |2\rangle[/tex]

You might have got more replies if you said what |0> and |2> are.

As it is, I can only suggest this:

[tex] \phi(x) ~=~ \langle x | \phi \rangle[/tex]

and hope that you know how to take the inner product between
a position eigenstate <x| and |2>, whatever that is.
