i have met a problem about the commutator of x and p.(adsbygoogle = window.adsbygoogle || []).push({});

[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?
