Helmholtz equation
another cool equation: Grad-Shafronov equation
\[\text{Helmholtz equation:}\ \ \ \ \nabla^{2}f=-k^{2}f\]^8aadd9
This is really interesting! Thank you! I slightly upgrade it: using $\eqref{eq1}$ so that the equation label can be refereed inline.
\(e=mc^2 \tag{3}\)
Einstein provides $\eqref{eq2}$ in his paper

\(x=y+1 \tag{2}\) ^b22f6d
As shown in [[ #^b22f6d|(2) ]], $x$ is greater than $y$
