The question is "two operators A,B do not commute". Is it true that(adsbygoogle = window.adsbygoogle || []).push({});

([A,B]psi) does not equal zero for any state psi?"

I'm not sure if there are any cases in which a state psi could produce this result (except for the obvious one where psi = 0 and there is no particle).

Thanks
