    Show that a unitary operator maps one ON-basis to another

    Homework Statement Given an inner product space V, a unitary operator U and a set \left\{\epsilon_i\right\}_{i=1,2,\dots} which is an orthonormal basis of V, show that the image of \left\{\epsilon_i\right\} under U is also an orthonormal basis of V Homework Equations The Attempt at a...
