I am using \begin{equation} \end{equation}
to number my equations in my text. But I normally mention these equations in the further text. E.g., In equation 3 ….
But if I change the former equation number I have to search in the text where I mentioned it.
Is there any way to link those numbers so when I change the equation number it automatically changes the furthers mentions about it in the text?

Something like this?
first
is an arbitrary identifier e.g.emc2
ora2o2h2
or whatever will have meaning for you.first
is a bad example because the equation might not always be first. While this won't bother LaTeX, it will confuse me!If you load amsmath, then you can use
\eqref{}
:cleveref is a popular package for cross-referencing of all kinds:
I prefer fancyref:
In this case the
eq:
part of the identifier tells fancyref what kind of thing is referenced, whereas cleveref tries to figure this out from the context.
