LyX ⇒ How to manually number equations in LYX?

[cphfynbo]

I have been a Scientific Workplace user for years but I have recently decided to opt for LyX instead. The transition has been much smoother than I had expected, but I am left with one very annoying problem; I cannot figure out how to manually number equations in LyX.

So, imagine that I would – for some reason – number my first equation “1”, the next one “B” and the third one “mythirdequation” – that is, “numbers” that are in no way related to the sections nor the title of the document, but just completely manually chosen. How would I do that? I have searched a lot, but without finding the solution. It is very easily done in Scientific Workplace.

Hi and welcome,

i am not a LyX user mmyself, so cannot tell you the LyX-way. With LaTeX and amsmath, which should always be loaded when dealing with maths, you can use \tag.

Code: Select all

\documentclass{article}
\usepackage{mathtools}
\begin{document}
\begin{equation}a\end{equation}
\begin{equation}b\tag{B}\end{equation}
\begin{equation}c\tag{something}\end{equation}
\end{document}

Dear Johannes_B,

I tried adding a "\tag{text}" field in the display. And it works perfectly well. Thank your very much!
