Math & Science ⇒ Limits after an Integral

[Willie]

Hello. I was trying to write an "expression after integration between to limits", but the result doesn't look good. For example in the following integral and expression after the integral:

Code: Select all

\int_0^9 x^2\,dx = \frac{x^3}{3}|_0^9

the expression |_0^9 doesn't produce a good looking result.

Does anyone know how to write it neatly?

I'm not sure if I understand your problem, but I assume you want a bigger vertical delimiter at the end of the right hand side of your equation. If so, try this:

Code: Select all

\int_0^9 x^2\,dx = \frac{x^3}{3}\biggl|_0^9

You can adjust this kind of delimiter manually.

Code: Select all

\documentclass[11pt]{article}
\usepackage[T1]{fontenc}

\begin{document}
  \[
    \int_0^9 x^2\,dx = \frac{x^3}{3}\Big|_0^9
  \]
\end{document}

For further information about math typesetting refer to the excellent »Math mode« document.

Hi. Thank you very much for your answers, this is what I wanted.

You also can use \left and \right commands (as I understand your problem).
Try this:

Code: Select all

\left.\int_0^9 x^2\,dx = \frac{x^3}{3}\biggl\right |_0^9
