Text Formatting ⇒ new function for references

[thorpn]

I am currently using the "\eqref{my_equation}" alot, however i almost always go on after this to write "section \ref{equations_section}". Is it possible for me to define a new function which does this for me and only takes the equations label as input ? (would save me alot of time when writting) ? or is it necesary to have the section(or subsection or whatever) as input also for such a section ?

Also, since i have started a post anyway.

Howcome i get a warning for this:

Code: Select all

$$
P:Delm \ae ngde(E) \mapsto R
$$

?

A MWE is necessary.

PS. Don't use $$ ... $$ for math expressions. Use \begin{equation} ... \end{equation} (or similar) instead.
