Math & Science ⇒ Problems in equation number at end of line

[horizon_83]

Hi,

I am using Texworks under MikTex and am unable to figure out a way to put the equation number at the end of the line. The equation number is generated just at the end of the equation but not at the end of the line.
I would really appreciate any help on this issue.

Thanks!!

Hi,

please post a minimal working example showing the undesired behaviour.

Hi,

I mean if the equation is a = b + c then it should give
a = b + c (1)

but it gives a = b + c (1)

I am using \begin{equation} a = b + c \end{equation}
I am just not able to identify the problem...
Thanks in advance!!

Again, please provide a minimal working example (MWE); instructions on how to build such a MWE can be found following the link I provided in my previous reply.

Hi,
the equation I want is:

\begin{equation}
\label{eqn2}
J_{1, n} ={\frac{1}{|\mathfrak{S}_n|}}{\sum_{\sigma \in \mathfrak{S}_n} {Fix(\hat{\sigma})}} = {\frac{1}{n!}}{\sum_{\lambda \in p(n)}{N(\lambda)}\cdot{\prod_{m = 1}^{n}{\lambda}_m! m^{\lambda}_m},
\end{equation}

but I want the equation number at the end of line not just after the equation as mine.
Thanks....

That is not a minimal working example; you have been instructed not once but twice to read about what a minimal working example is. If you want help, you're going to have to do so.

As frabjous mentioned, that is not a minimal working example; however, one sees the problem at once: there's a mismatched brace; a closing brace is missing, and after suitable completion:

Code: Select all

\documentclass{book}
\usepackage{amsmath,amssymb}

\begin{document}

\begin{equation}
\label{eqn2} 
J_{1, n} ={\frac{1}{|\mathfrak{S}_n|}}{\sum_{\sigma \in \mathfrak{S}_n} {Fix(\hat{\sigma})}} = {\frac{1}{n!}}{\sum_{\lambda \in p(n)}{N(\lambda)}\cdot{\prod_{m = 1}^{n}{\lambda}_m! m^{\lambda}_m}, 
\end{equation} 

\end{document}

the compilation ends with an error and the tag appears in the wrong position. The problem is solved once the formula is typeset correctly:

Code: Select all

\documentclass{book}
\usepackage{amsmath,amssymb}

\begin{document}

\begin{equation}
\label{eqn2} 
J_{1, n} = \frac{1}{|\mathfrak{S}_n|} \sum_{\sigma \in \mathfrak{S}_n} 
{Fix(\hat{\sigma})} = \frac{1}{n!}\sum_{\lambda \in p(n)} N(\lambda) \cdot \prod_{m = 1}^{n}{\lambda}_{m}! m^{\lambda}_{m}, 
\end{equation} 

\end{document}
