xinychen / latex-cookbook Goto Github PK

Under each article, the page corresponding to "Previous Section" or "Next Section" appears with 404 Unreachable. The link they are referring to is wrong.
This problem exists in both version 1 and version 2.
eg: chapter2-section2

"Previous Section"

"Next Section"

as the tittle says。Can't see anything after chapter 3。

\documentclass[12pt]{article}
\begin{document}

Equation~\eqref{eq1} shows a simple formula.

\begin{equation}\label{eq1}
x+y=2
\end{equation}

\end{document}

error: Undefined control sequence.
It seems shoud use package amsmath to make \eqref work,
so correct code is

\documentclass[12pt]{article}
\usepackage{amsmath}
\begin{document}

Equation~\eqref{eq1} shows a simple formula.

\begin{equation}\label{eq1}
x+y=2
\end{equation}
