Im having problems with the vertical space that the $$ $$
command creates. For example:
\begin{multicols}{2}
\begin{enumerate}
\item \[\sum\limits_{k=1}^{\infty}\frac{k^2e^{-2k}}{k^2+1}\]
\item $$\sum\limits_{k=1}^{\infty}\frac{\left|\sin{k^4}\right|}{\sqrt{k^4+1}}$$
\end{enumerate}
\end{multicols}
This creates a vertical space between the \item
and the object in the $$ $$
command. I just want to eliminate this effect. One possible solution is to use the fast math mode: $object$
. But, this doesn't satisfy me.
