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

$$F = \int {f(x) dx}$$

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

The right-click trick should work on those. Or control-click if you're using a Mac, like I am.

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

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.

[itex]\int_a^b {f(x) dx}[/itex]

itex [itex] \int_a^b {f(x) dx}[/itex]

itex with \displaystyle [itex] \displaystyle\int_a^b {f(x) dx}[/itex]
