Is it possible to achieve something like this in LaTeX?
I want a curved arrrow pointing from 1st line to the other line and is coupled with an equation number which indicates the equation used. I want to be able to specify equation used manually like for example \eqref{2.10}
.
I have learned TikZ a bit and found something what might look like a solution:
\begin{tikzpicture}
\path (0,1) coordinate(c1)
(-0.5,0.85) coordinate(c2)
(-0.5,0.15) coordinate(c3)
(0,0) coordinate(c4)
(-1,0.5) coordinate(c5);
\draw [-latex] (c1) .. controls (c2) and (c3)
.. (c4);
\draw (c5) node [anchor=east] {\text{\eqref{2.10}}};
\end{tikzpicture}
This produces a lovely arrow (below) which i don't know how to put on the left side of two rows of an equation. Please someone give me advice on this.
Additional question:
Is it possible for this arrow to dynamically change coordinates c1, c2, c4 and c4 if equation rows are sepparated more or less?
