Homework Help: Quantum Mechanics: Eigenvaules, and orthogonality

  1. Mar 23, 2004 #1
    Hey, I've been trying to solve this problem it sounds simple but i don't know where to start:

    If [tex]\phi_{1}[/tex] and [tex]\phi_{2}[/tex] are normalised, have the same eigenvalue and obey [tex]\int \phi_{1}*\phi_{2}d\tau = c[/tex] find the linear combination that is normalised and orthogonal to [tex]\phi_{1}[/tex]

    Thanks

    NB: * denotes a complex conjugate,

    Thanks
