The three lowest eigenstates of some system are denoted by 01 (2), 02 (xv) and 03 (x) with corresponding eigenvalues E1, E2 and E3. The wavefunction V (x) is a superposition of the three eigenstates such that y(x) = N[01(x)+602 (x) + 203 (x)], where N is a normalization factor. Assuming that the three eigenstates 01 (2c), 02 (x) and 03 (x) are normalized and their eigenvalues are non-degenerate, what is the correct value for the normalization constant N
