    How do we show that the greatest accuracy in the |mn> state is |n| = m for the Mx and My components?

    If M is an angular momentum operator, then Mx and My =0 for |n|=m.

    Yes M is an angular momentum operator. I also know that the components Mx and My do not commute. However, I do not understand how to show the greatest accuracy.

    Are you saying that Mx and My are orthogonal since they do not commute?
