Here is a labeled equation:
|
||
|
|
$$x+1\over\sqrt{1-x^2}\label{ref1}$$
|
||
|
|
with a reference to ref1: \ref{ref1},
|
||
|
|
and another numbered one with no label:
|
||
|
|
$$x+1\over\sqrt{1-x^2}$$
|
||
|
|
This one uses \nonumber:
|
||
|
|
$$x+1\over\sqrt{1-x^2}\nonumber$$
|
||
|
|
<p>
|

Here's one using the equation environment:
|
||
|
|
\begin{equation}
|
||
|
|
x+1\over\sqrt{1-x^2}
|
||
|
|
\end{equation}
|
||
|
|
and one with equation* environment:
|
||
|
|
\begin{equation*}
|
||
|
|
x+1\over\sqrt{1-x^2}
|
||
|
|
\end{equation*}

This is a forward reference [\ref{ref2}] and another \eqref{ref2} for the
|
||
|
|
following equation:
|
||
|
|
$$x+1\over\sqrt{1-x^2}\label{ref2}$$
|
||
|
|
More math:
|
||
|
|
$$x+1\over\sqrt{1-x^2}$$
|
||
|
|
Here is a ref inside math: \(\ref{ref2}+1\) and text after it.
|
||
|
|
|
||
|
|
\begin{align}
|
||
|
|
x& = y_1-y_2+y_3-y_5+y_8-\dots
|
||
|
|
&& \text{by \eqref{ref1}}\\
|
||
|
|
& = y'\circ y^* && \text{(by \eqref{ref3})}\\
|
||
|
|
& = y(0) y' && \text {by Axiom 1.}
|
||
|
|
\end{align}
|
||
|
|
|
||
|
|
Here's a bad ref [\ref{ref4}] to a nonexistent label.
|
||
|

An alignment:
|
||
|
|
\begin{align}
|
||
|
|
a&=b\label{ref3}\cr
|
||
|
|
&=c+d
|
||
|
|
\end{align}
|
||
|
|
and a starred one:
|
||
|
|
\begin{align*}
|
||
|
|
a&=b\cr
|
||
|
|
&=c+d
|
||
|

\end{align*}
