I have an equation in my document which is unbreakable and does not fit on one line using the twocolumn
global option. Am I forced to shrink the text size here? And how do I go about doing it? \resizebox
does not function in math mode.
\documentclass[twocolumn]{ltxdoc}
\usepackage{amsmath}
\begin{document}
\begin{equation}
\sum_{q_\mathrm{total}=0}^{q_A+N_A+q_B+N_B-2}\left(\sum_{q_A=0}^{q_\mathrm{total}}\left(\binom{q_A+N_A-1}{q_A}\binom{q_B+N_B-1}{q_B}\right)\right)x^{q_\mathrm{total}}
\end{equation}
\end{document}
\small
or whatever works before the equation, or just simply introduce variables for the subterms so it fits
