I have problem of alignment in the following, please check and suggest solution:

\begin{enumerate}
\item
\begin{equation}
    \kappa_{a,b}(t)=\begin{cases} 
            e^{at}, & 0\leq t<\infty,\\
            e^{bt}, & -\infty<t<0.                              
            \end{cases}
\label{eq:kappa-ab-t}
\end{equation}
\item
\begin{equation}
        \beta(x)=\frac{x^m}{\mu_n^{2k'-1}}
        \label{eq:beta-x}
\end{equation}
    for m=1, 2, 3, \ldots, n=1, 2, 3, \ldots, k'=0, 1, 2, \ldots.
\end{enumerate}

In output equations doesn't appear in the same line as of item number, appears at center of second line. I want it to appear in the same line with left alignment and corresponding equation numbers to right of page.

You could use the flalign environment from the amsmath package with the numbers in the first column. 

\documentclass{article}
\usepackage{amsmath}
\newcounter{thing}
\setcounter{thing}{0}
\newcommand\leftno{\addtocounter{thing}{1} \arabic{thing}.\quad }
\begin{document}
\begin{flalign}
\leftno &   \kappa_{a,b}(t)=
  \begin{cases} 
   e^{at}, & 0\leq t<\infty,\\
   e^{bt}, & -\infty<t<0.                              
   \end{cases}
    \label{eq:kappa-ab-t} & \\
\leftno & \beta(x)=\frac{x^m}{\mu_n^{2k'-1}}
        \label{eq:beta-x} & \\
\setcounter{thing}{27} %Test alignment of two digit numbers
\leftno & \beta(x)=\frac{x^m}{\mu_n^{2k'-1}} & 
\end{flalign}
    for m=1, 2, 3, \ldots, n=1, 2, 3, \ldots, k'=0, 1, 2, \ldots.
\end{document}

Numbering on both the left- and right-hand sides looks rather strange, though.

  • @ Ian, Thanks. This has solved my problem. Its listing of some functions under a chapter which will be referred further in other chapters, so may feel at first strange. – Madhu Feb 07 '13 at 23:20
