I am asked a problem where I'm supposed to integrate the expectation value of a dynamic variable (operator) to solve a differential equation. OK, is the expectation value supposed to be a variable?(adsbygoogle = window.adsbygoogle || []).push({});

But it seems to me like its a definite integral over allspace and thus is a number. So integrating it would just be like integrating a constant.

What does this operation of integrating the expectation value of an operator even mean conceptually?
