i have met a problem about the commutator of x and p.
[x,p]=ihbar
/p> is the eigenstate of momentum operator p.
<p/xp-px/p>
=<p/xp/p>-<p/px/p>
=p<p/x/p>-p<p/x/p> the second term is got by the momentum operator p acting on
the left state.
=0
so i get zero! is there anyone can point out where i am wrong?
