Fine-tuning math formulas

Though LaTeX's typesetting of formulas is usually excellent, there are situations when the layout can require improvement. This recipe shows quick fixes.

Getting ready

Let's have a look at misalignment and spacing, issues with subscript and superscript that can easily occur:

1. Open the following sample document with your LaTeX editor. You can take it from the code archive provided with the book or copy and paste from the e-book:

   \documentclass{article}
   \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}

2. Compile, and take a look at the formula:

Although the LaTeX code is fine, you will notice that several ...
