Thanks a lot!!

The formulas are numbered, but the frame should not include the number.
Here is the code of the equation without frame:

\begin{alignat}{1}
\Delta\delta g_{T} & =\frac{1}{l_{m}}\left[\delta\mathbf{g}\cdot\mathbf{nn}\cdot\Delta\mathbf{m}+\delta\mathbf{m}\cdot\mathbf{nn}\cdot\Delta\mathbf{g}-\xi ...

Thanks a lot. I tried and it works. However I still have a problem when I need to insert aligned equations (using AMS). Can you please help???
Thanks!!!

Hi everyone,

I need to put some equations into a box (one box per equation, or in some cases one box surrounding two equations located on the same line). Can anyone explain how can I do that? I suppose I should add some LateX code, but how exactly?

Thanks a lot in advance!

Hi everyone,
I am a new user of Lyx and am trying to create a poster. My intention is to use the "article" class and the A4 format. However I need to place the text in, say, three columns. On top and at the bottom I also need to place two figures of small height and full width, with the conference ...

\numberwithin{equation}{section} The the equations will be numbered by section. Not only in the appendix, also in the main text, but I think this would be consistent. Remember that \numberwithin doesn't come from LaTeX. It comes from the amsmath package.

Of course it's also possible with the article class. It's just not the default behaviour.
Use this line inside your document preamble:

Hi Laura,

welcome to the board!
Which document class are you using? For instance with the report class it's the default behavior. After \appendix the equations will be numbered (A.1) and so on.

Hi Stefan,

Thanks for the reply! I'm using the article class, because I need abstract ...

Hi everyone,
I am a new user of Lyx and am trying to number equations in a technical paper. In the appendices of the paper, I would like the numbering to restart and to have the letter of the appendix before the number (ex. A.1, A.2, etc., then B.1, B.2,...) Couldn't find the way to do it in Lyx ...
