Hello everyone! I have some questions about equatuons: 1) I want to get from rst source latex code like this: How can I do this? Would it be ok just to use two math:: directives each with :label: option? The question is on alignment. \begin{eqnarray} m_1\ddot{x}_1+(k_1+k_2)x_1k_2x_2 & = & u_1, \label{spmass1}\\ m_2\ddot{x}_2k_2x_1+(k_1+k_2)x_2 & = & u_2 . \label{spmass2} \end{eqnarray} 2) Is it possible to get labels for equations like these: \begin{equation} \dot{x}(t) = f(t, x, u), \label{ctds1} \end{equation} \begin{equation} x(t+1) = f(t, x, u), \tag*{(\ref{ctds1}d)} \label{dtds1} \end{equation} ? I mean I want labels to look like (1) and (1d), for example. 3) What about referencing equation from another file (chapter)? Is it possible? Lukashevichus Ksenia.
