I've just done a textbook exersize to calculate (H,x) and ((H,x),x) for H= p^2/2m +V.(adsbygoogle = window.adsbygoogle || []).push({});

Having done the manipulation, my next question is what is the significance of this calculation. Where would one use these commutator and double commutator relations?
