 Yes, it' a kind of Fourier trick. If you look at the equation 2.144, then you would understand how this proof has been made.

+For Chap <f_p'|f_p> = d(p-p'), look at this equation, if p'=p, then d(p'-p)=d(0), and d(p'-p)=0 otherwise. Mathematically, d(0)=1, the physical meaning behind it is the orthonormal of wave function in momentum space.

 What is a good method for finding the determinant of an nxn matrix? Do you think we will need to be able to find such a determinant in this class? Why or why not?

+Must all non-degenerate energy eigenfunctions be parity eigenfunctions?
