General ⇒ Terms beside equations

[rasole]

Hi there,

I need to write the term of my equations beside the equation number, like [Hz] (Eq. 2.20).
The alignment of the equations must not be affected.
Any ideas?

Thanks

[Juanjo]

Actually no, it's not the Eq.-thing but the [Hz] thing
I'll just attach an example

Anyway, this has side-effects if you use \eqref to cite equations. Your query is not clear enough, so perhaps there are bettter ways to proceed. Has [Hz] to appear in all equations? What is really that? By the way, which is the code you used to get the attached jpg? Why that code is not good enough?

The picture is made in MS Paint (shows what I want the final result to look like). I need help designing the code, so a can place such a term, the ['term'], after an equation, as I like.

OK about the picture, but you should still complete your answer. Does that term vary from equation to equation? Do you require to control it somehow?

Yes I need to supply a different unit to every of my equations. The following code works, but makes errors, why I don't know

There is an interesting document you should take a look at [1]. Seems to be written by our member daleif. A search in the forum may yield other suitable results.

Sorry, I'm not that good at this yet, so if I could get some kind of example. Maybe it's something about making a 3 column table (not actually a table because of the missing equation number then).

You can get a lot of examples by using the search function of the forum. Use the align environment provided by the amsmath package.
