LyX ⇒ How to lable an equation other than numbering

[zarger1981]

I try to number my equations in my own way,e.g., (A.1.2), instead of the default numerical numbering (1) (2)..
But whenever I label an equation, for example, with "eq:A.1,2", it still turns out to be (1) (2)...
An I find that even I just label "eq:", it still comes out with (1) (2)...
Does anyone know how to label equations in the way I want? Thank you.

Hi,

you could use the \tag command, like \tag{A.1.2}, or redefine the \theequation macro. The amsmath documentation could be helpful for your, perhaps more of the math tutorials/documentation here: Mathematics with LaTeX.
