I Prove principal axes of moment of inertia are orthogonal

    What does the first two equations mean? I can't make sense of the notations. Does it mean taking the x axis to be parallel to one principal axis and the y axis to be parallel to the other principal axis?

    EDIT: I figured it out. They are eigenvalue equations.
