Near the end of Chapter 9, Writing Math Formulas, it's mentioned that with the mathtools package we can align limits of consecutive math operators vertically.

Do you have an example how to do that?

Here is an example taken from the LaTeX Cookbook, Chapter 10, Advanced Mathematics:

Code: Select all

\documentclass[border=10pt,preview]{standalone}
\usepackage{dsfont}
\begin{document}
\[
  \lim_{n\to\infty} \sup_{x\in\mathds{R}} f_n(x^2)
  < n \Big(\sum_{x\in\mathds{R}, n\in\mathds{N}}
  \big| f_n(x^2) \big| \Big)
\]
\end{document}

We get:

Now we load the mathtools package, use the \adjustlimits command right before the \lim operator, insert \smashoperator to remove that big white space before \sum, and change x^2 to \cramped{x^2} to slightly lower the exponent, at both places:

Code: Select all

\documentclass[border=10pt,preview]{standalone}
\usepackage{dsfont}
\usepackage{mathtools}
\begin{document}
\[
  \adjustlimits\lim_{n\to\infty} \sup_{x\in\mathds{R}}
    f_n(\cramped{x^2})
    < n \Big( \smashoperator{\sum_{x\in\mathds{R},
    n\in\mathds{N}}}
    \big\lvert f_n(\cramped{x^2}) \big\rvert \Big)
\]
\end{document}

We get:

You can see that the limits onm the left side have been adjusted vertically, and some more mentioned finetuning. The

mathtools manual gives further information.
