Integrating imaginary units and operators

[Dean Navels]

When integrating terms including the imaginary unit i and operators like position and momentum, do you simply treat these as constants?

Yes, for example when you have the integral

$\int_a^b ix dx$ ,

you can take the $i$ outside the integration like any constant:

$\int_a^b ix dx = i\int_a^b x dx$ .

Thank you very much, sir!
