This question is related to this one:
I have this code:
\documentclass[11pt]{article}
\pagestyle{empty}
\usepackage{blindtext}
\renewcommand{\baselinestretch}{1.1}
\usepackage{amsmath}
\makeatletter
\def\newmaketag{%
\def\maketag@@@##1{\hbox{\m@th\normalfont\normalsize##1}}%
}
\makeatother
\begin{document}
\flushbottom
\section{Section}
\blindtext
{\small%
\newmaketag\begin{equation}
\frac{2 x_{1} + 2 x_{2} + 2 x_{3} + 2 x_{4} + 2 x_{5} + 2 x_{6} + 2 x_{7} + 2 x_{8} + 2 x_{9} + 2 x_{10} + 2 x_{11} + 2 x_{12} + 2 x_{13} }{z}
\end{equation}}\relax
\end{document}
As you can see in the screenshot:
the baselinestretch of the last line of the paragraph above the equation is wrong. How can I fix it?
Note. Please, please, really please! Don't waste your time (and mine) telling me I shouldn't use \small
to resize an equation (or suggesting me others techniques to resize equations). I do have my own reasons to do that (in some cases).
