I have the following formula in my LaTeX code:

$ \mu_{x_{t}} = E(x_{t}) = \int_{a}^{b} $

This gives me the follwing in my document

Now I tried to use \bigint, but that gives me too thick integral... what do I need to do to get the same thickness but with more height?

More height comes with display mode:

\[ \mu_{x_{t}} = E(x_{t}) = \int_{a}^{b} \]

Display mode

Or you can only make the integral larger:

$ \mu_{x_{t}} = E(x_{t}) = {\displaystyle \int_{a}^{b} } $

Displaystyle

There are a few ways to change the appearance- \displaystyle is one of them, and you can also use \limits, or even a combination:

enter image description here

\documentclass{article}

\begin{document}

\begin{itemize}
    \item $ \mu_{x_{t}} = E(x_{t}) = \int_{a}^{b}$
    \item $\mu_{x_{t}} = E(x_{t}) = \int\limits_{a}^{b} $
    \item $ \mu_{x_{t}} = E(x_{t}) = \displaystyle\int_{a}^{b} $
    \item $ \mu_{x_{t}} = E(x_{t}) = \displaystyle\int\limits_{a}^{b} $
\end{itemize}

\end{document}

For future reference, have a look at the Not so short Introduction to LaTeX

  • Thank you! I will =) It's you know sometimes just easier to ask 5 second thing from someone than to read whole book. Sometimes you do find the 5 second thing right away and sometimes you don't and when you don't it usually can scale up to hours, because when you look at one thing then you need to reference another thing and then another and that takes too much time for every single character in thesis ;) – jjepsuomi Jan 25 '13 at 18:03
