I'm a LyX beginner so please don't worry about stating the obvious.
I'm numbering equations by section in my document. That's working fine. However, when I refer to the same equation later on in the text I can't see how I can give it its original reference number.
So if y=x+2
is numbered as 4.2.2
, I want to be able to give y=x+2
the same number next time I use it. Is there a straightforward way of doing this? I'm assuming I have to sandwich the equations in code of some sort.
I'm using the scrbook
(Koma-script) document class. I'm using the modules: Theorems (AMS), Theorems Numbered by Chapter, Number Equations by Section.
The LaTeX preamble is:
\usepackage{microtype}
\usepackage {hyperref}
\usepackage{amsmath}
\numberwithin{equation}{section}
\setkomafont{captionlabel}{\bfseries}
To date I've been changing the code in my LyX documents using Windows Notepad. Is that the best way of editing code?
