Footnotes next to Equation Number

Post by shiningchihuahua »

Hello,

I want to put a footnote in an equation, but not at the end of the equation where it could be confused as a power, but next to the equation number at the side. For example if the equation was numbered (1), then i could put a superscript letter/number after it which would be a footnote.
I have read about \footnotemark but I'm not sure where I would place that to make the footnote appear next to the equation number. FYI, im using \begin{equation} & \end{equation} with the equation in between those.

Any help with this problem would be greatly appreciated

Miles

Update!

I've worked out this:

Code: Select all

\begin{equation}\refstepcounter{equation}
x=y \tag{\theequation\footnotemark}
\end{equation} \footnotetext{thefootnote}
but it puts the footnote symbol inside the brackets of the equation number. Any ideas on how to get this outside the brackets?

Done it!!

Code: Select all

\begin{equation}\refstepcounter{equation}
x=y \tag*{(\theequation)\footnotemark}
\end{equation} \footnotetext{thefootnote}
If you put \tag* then it lets you write whatever you want!

Hope this comes in handy to any LaTeX users in the future.
