With the following syntax:
$ \int_{a}^{b} Foo dx $
I have the limits on the right of the integral sign. I'd like to have them under and above.
Do I need a package for that? Is there a way similar to
\lim\limits_{bla}
that doesn't require a recognized math operation?
This is what you're looking for I believe.
Below the code snippet that places the integration limits under and above the integral sign.
\[
\int\limits_a^b f(x) \, \mathrm{d} x
\]
