## How do I write an integral from a to b in latex?

As the title suggests, I can only see how to write an integral like:

But how would I write an integral like the following?

Put a subscript and a superscript on the \int, e.g. \int_{a}^{b}

It's just an image.
 Mentor Here's the actual LaTeX for phosgene's two integrals: $$F = \int {f(x) dx}$$ $$\int_a^b {f(x) dx}$$ The right-click trick should work on those. Or control-click if you're using a Mac, like I am.

As long as the subscripts/superscripts are single characters, as in the above, you can omit the braces around the sub-/superscript. The following will render exactly the same:
\int_a^b

When there are two or more characters (e.g. 2x, -3, etc.) you need the braces around the entire expression, as in this example:
\int_{-2}^{3x}

mine looks smaller for some reason.

$\int_a^b {f(x) dx}$
