gather

[David Arnold <darnold@northcoast.com>]

All, 

The default behavior of gather is to center a group of equations. By
default, each one is numbered. Try:

\documentclass{article}
\usepackage{amsmath}

\begin{document}

\begin{gather}
F(x)=\int_0^x f(t)\, dt\\
F'(x)=f(x)
\end{gather}

\end{document}

Compare with:

\usemodule[amsl]

\starttext

\startgather
F(x)=\int_0^x f(t)\, dt\\
F'(x)=f(x)
\stopgather

\stoptext

In amsmath, if we don't want the individual equations numbered, we use the
* version. Try:

\documentclass{article}
\usepackage{amsmath}

\begin{document}

\begin{gather*}
F(x)=\int_0^x f(t)\, dt\\
F'(x)=f(x)
\end{gather*}

\end{document}


I hope this helps those who are working on these issues.
