Putting the integration bounds below/above the integration operator [duplicate]

Show inline math as if it were display math

Yesterday I've stumbled upon an article which covered just that, but I can't find it anymore.

How can I put the integration bounds above/below the integration operator instead of the default, where they're next to the symbol and push the integration term to the right?

• Do not use inline mode, but displaymath mode instead! See p.12 and following of mathmode.pdf and Show inline math as if it were display math! – hakaze Aug 14 '12 at 9:10
• I'm using the equation environment. I wasn't aware that it didn't use display mode. Thanks! – Joe Doe Aug 14 '12 at 9:18
• We can hardly know what exactly you do unless you provide a minimal working example. Anyways, I believe that the limits positioning is covered in the question linked by @hakaze. – yo' Aug 14 '12 at 9:28

Use the \displaylimits command.
\documentclass{article}
$\int_a^b f(x) \, \mathrm{d} x \quad \int\displaylimits_a^b f(x) \, \mathrm{d} x$

• Just \limits will also do. – Torbjørn T. Aug 14 '12 at 10:29
