I am fairly new at this and trying to put a table containing a brief description of the equations I use, into my thesis. This has proven to be quite an irritating problem. I have found a nice concise solution on the web (http://www.latex-community.org/forum/viewtopic.php?f=5&t=428) which has been very helpful (thanks to gmedina). The solution uses the tocloft package to define a new list.

The problem I now have, is that as the equation numbers get longer the text description and equation numbers overlap, can anyone help me with this? Also if anyone can explain the command clearly it be very helpful. Below is a MWE I am using texmaker and Miktex.

tocloft provides \cft<set>numwidth for the width of the number associated with an entry <set>. In your case, <set> is myequations, so we can adjust \cftmyequationsnumwidth in the following way:

I used 2.5em, where the default is usually 1.5em.

I expanded upon the previous answer to define a command that you can use like so:

\noteworthy{a^2 + b^2 = c^2}{Pythagorean theorem} 

And it will automatically label, reference, box, and list the equations that I consider noteworthy. I'm really happy with the result.

Note that the red squares just highlight hyperlinks, they're not visible on the pdf.

enter image description here

And then the equation is numbered, boxed, labelled with text (that matches the list of equations), and gets a label to allow us to reference it.

enter image description here

Minimum viable example:

\documentclass{article}
\usepackage{tocloft}    % for list of equations
\usepackage{ragged2e}   % to undo \centering
\usepackage{hyperref}   % to make references hyperlinks
\usepackage{glossaries} 

% define list of equations
\newcommand{\listequationsname}{\Large{List of Equations}}
\newlistof{myequations}{equ}{\listequationsname}
\newcommand{\myequations}[1]{
   \addcontentsline{equ}{myequations}{\protect\numberline{\theequation}#1}
}
\setlength{\cftmyequationsnumwidth}{2.3em}
\setlength{\cftmyequationsindent}{1.5em}

% command to box, label, reference, and 
% include noteworthy equation in list of equations
\newcommand{\noteworthy}[2]{
\begin{align} \label{#2} \ensuremath{\boxed{#1}} \end{align} 
\myequations{#2} \centering \small \textit{#2} \normalsize \justify }

\begin{document}

\listofmyequations \pagebreak

\noteworthy{P(\bigcup_{n=1}^n A_n) \leq \sum_{n=1}^n P(A_n)}{Boole's inequality}

Where the events $A_n$ are disjoint, then the inequality 
in equation \ref{Boole's inequality} becomes an equality.

  • This snippets augments the accepted solution with the missing indentation nicely. – maxik Jun 5 '18 at 7:01
