I want to create a citation like:  [15, Eq.(3.27)]  Do you know how can I do it using \cite?

I would like to cite the item (iii) of proposition 3 of a reference. How can I do it? Which ways do you suggest? This is a question not only about LaTeX, but also about style. One option I have seen to cite pages of a reference is \cite[p.~333]{Audet}. Is there something similar to cite theorems, propositions and so on?

I have occasionally wanted to refer to a range of equations in my document.  So far, I've been using Equations~\eqref{firstEquation}~--~\eqref{lastEquation}, which produces something like "Equations (5) - (12)".  I recognize that this could make it harder to maintain the document if equations get shifted around, but I still prefer it to something like "Equations (5), (6), (7), (8), (9), (10), (11), and (12)".  Is there a standard or accepted way to refer to a range of equations like this?  Or should I just keep doing whatever looks best to me?

I did the following base case $n = 5$ $$\begin{align*}     4(5) &amp;\lt 2 ^5\\     20 &amp;\lt 32 \end{align*}$$ So true.  $$\begin{align*}     4n &amp;\lt 2^n\\ n &amp;\lt 2^{n-2}\\ \log_2(n)+2 &amp;\lt n \end{align*}$$ But I don't think this is right. Where do I add in the $(n+1)$.

I'd like to type a citation within the text and another citation inside the parenthesis for the year, something like this:     The work of Author 1 (year; cited by Author 2, year)   For this, I've tried different options of the \textcite command but without results. Also I saw the solution posted , which works for multiple citations within parenthesis but not for in-text citations.  Any suggestion?

This question led to a new package:      I want to reference to citations from other file. Similar to what xr package does to labels, but I want to apply it for the bibliography.  If I'm able to do \cite{someone} in the main file, and it creates let say the number [4], I want to do the same \cite{someone} in a second file, and also create the same number [4]. Similar to what xr does with the labels.  By the way, I tried to add the main.bbl file from the main file. However, that adds all the references to the end of the second file. I want to avoid this.  Is there any package that accomplish this?

I want to compare the output of \ref to a number in LaTeX. I thought it would be easy but after spending lots of hours surfing the net I still don't know the answer. I found similar questions on this site but I would prefer a solution that does not require another package to be included, so that I can see clearly how the \ref command (and some others) works. I tried a lot of things, some of which I share below, therefore my question is rather long, I'm sorry about that. First, I tried the following codes (the resulting error messages are shown after a % sign):  \begin{equation} \label{eq:myeq}   a=b   \end{equation}  \ifnum\ref{eq:myeq}=1 true\else false\fi % error: "Missing number, treated as zero."  \expandafter\ifnum\ref{eq:myeq}=1 true\else false\fi % error: "Missing number, treated as zero."  \edef\blabla{\ref{eq:myeq}} % error: Incomplete \iffalse; all text was ignored after line 42. \ifnum\blabla=1 true\else false\fi \expandafter\ifnum\blabla=1 true\else false\fi   Of course, \ref{eq:myeq} gave the expected result, namely 1.  Then, I found the definition of \ref using the latexdef ref command:       \ref:   macro:#1->\expandafter \@setref \csname r@#1\endcsname \@firstoftwo {#1}   Further examining \@setref and \firstoftwo, I concluded that the equation number (together with the page number) is stored in a control sequence called \r@eq:myeq. More precisely, the content of \r@eq:myeq is {1}{1} where the first number is the equation number and the second number is the page number. (The output of \expandafter{\csname r@eq:myeq\endcsname} is 11.) If I understand well, in order to obtain the equation number we have to expand \csname r@eq:myeq\endcsname by only two levels to get {1}{1} (the first level of expansion yields \r@eq:myeq), and then we choose the first argument by \@firstoftwo. Since there is no simple way to expand a control sequence by only one level, it is done in a rather circuitous (say tricky) way by \ref. This I could also reproduce by the following code:  \def\sth#1#2{\expandafter #2#1} \makeatletter \expandafter\sth\csname r@eq:myeq\endcsname\@firstoftwo \quad \ifnum1=\expandafter\sth\csname r@eq:myeq\endcsname\@firstoftwo true\else false\fi \makeatother   which resulted in 1   true. So far so good but there are still a few questions. First of all, if the above code works then why does the code with \ifnum1=\ref{eq:myeq}... fail (see above)? Seemingly, the two "algorithms" are doing the same. Second, the above code works only if the auxiliary file (with aux extension) contains the label definition. If it doesn't (the reference is undefined) then LaTeX gives the following error message: Missing number, treated as zero. How can I write a code that works even if the reference is undefined? Thank everybody who read all my above struggle and I would appreciate if someone shed light on the points that were not clear to me and who corrected me where I was wrong and confirmed where I was correct. Unfortunately the whole command syntax of (La)TeX is still very strange to me.

By default the style is  \renewcommand{\theequation}{\thechapter.\arabic{equation}}   for example                  x+y =4         (2.1)   How to put \dots in front equation numbering such as              x+y =4      ...(2.1)   while in the text reference remain (2.1).  and how to make it for the array by using \begin{eqnarray} \end{eqnarray}        x = y+ 4                   -Z+ E                  + 4gh     ...(2.1)

How can I do multiple citations with page numbers using bibLaTeX/biber?  I have tried \cite[2,3,4]{ref1,ref2,ref3,ref4} but it doesn't work.

A number of related questions have already been asked about this issue:       and even    But I'm still confused by the conflicting suggestions that have been given so far. So I'm trying again.  Which should be the preferred command to produce a displayed equation in my LaTeX documents?  So far the suggestions indicate that one should use \[ ... \], maybe \begin{equation*} ... \end{equation*}, or maybe even the gather* or align* environments from amsmath.  And one should definitely avoid using either $$...$$ or the eqnarray environment.  Now I have to say that, from a language perspective, I have a strong preference for the equation* environment because it is less cryptic than the \[ ... \] notation and it is  the most accurate.  So, is it fine to use equation*? Maybe only after loading amsmath? Or should the equation/equation* environment be redefined to something else so that spacing, package support, or whatever is improved?

Hi I wish to number equations  with a list environment   \begin{itemize} \item Lol \begin{equation} y_t=h_t(\hat{x}_{t|t-1}) \end{equation} \end{itemize}   I want  y_t=h_t(\hat{x}_{t|t-1}) in the same line of Lol... Can you help me to find out a way?

I use a custom cite command cite which puts the citation on first use in the footer. The problem is that there is no possibility to reference a page or section with this cite command. example: \cite[p. 12]{somebibref} ignores the optional parameter. The citation should be in brackets like this: ...Lorem explains [1, p.12]... This is the code snipped i got but i dont know how to modify it for my purpose.  What do I need to modify to add the additional parameter only in the citation in the text not in the footer?  \makeatletter  \newtoggle{cbx@togcite}  % remove doi, eprint and url from footnote %\renewbibmacro*{doi+eprint+url}{}%  % Citation number superscript in brackets \renewcommand\@makefntext[1]{%   \iftoggle{cbx@togcite}     {\@textsuperscript{\normalfont[\@thefnmark]}\enspace #1}     {\@textsuperscript{\normalfont\@thefnmark}\enspace #1}%   \global\togglefalse{cbx@togcite}}  \renewcommand\@makefntext[1]{%   \iftoggle{cbx@togcite}     {\normalfont[\@thefnmark]\enspace #1}     {\normalfont\@thefnmark\enspace #1}%   \global\togglefalse{cbx@togcite}}  \DeclareCiteCommand{\cite}[\cbx@superscript]%   {\usebibmacro{cite:init}%    \let\multicitedelim=\supercitedelim    \iffieldundef{prenote}      {}      {\BibliographyWarning{Ignoring prenote argument}}%    \iffieldundef{postnote}      {}      {\BibliographyWarning{Ignoring postnote argument}}}   {\usebibmacro{citeindex}%    \usebibmacro{sfcite}%    \usebibmacro{cite:comp}}   {}   {\usebibmacro{cite:dump}}  \newbibmacro*{sfcite}{%   \ifciteseen   {}   {\xappto\cbx@citehook{%    \global\toggletrue{cbx@togcite}%    \noexpand\footnotetextA[\thefield{labelnumber}]{%      \fullcite{\thefield{entrykey}}\addperiod}}}}  \newrobustcmd{\cbx@superscript}[1]{%   %\mkbibsuperscript{\mkbibbrackets{#1}}%   \mkbibbrackets{#1}%   \cbx@citehook%   \global\let\cbx@citehook=\empty}  \let\cbx@citehook=\empty  \endinput

I want to write an equation with bold extended brackets.  For instance in:   \left[ \frac{1}{2} \vec{\nabla} \times \vec{v} \right]   I want \left[ and \right] to be bold. I already tried  nothing is doing the trick.

in questions, answers, and comments. Can we get something like this going on Stack Overflow?  I think it’d be appropriate as I at least pretty often want to write something like n^2 and would benefit greatly from prettier markup.

I want to be able to  write the following in LaTeX      We make the further assumption that \begin{equation} \label{eqn:assumption} There is a bounded linear operator     $B:X\to X^*$ such that $B^*=B$ and the operator $JB$ is an extension of $T'(0)$\end{equation}   and get a nice output, in such a way that this whole chunk of text along with the math can be referenced later. Of course I can write text inside the equation environment using \text{}, but when I tried this the spacing was all wrong. Can anyone suggest a solution to this?

I want to write an equation in latex like the following one.   But I can not align a set of numbers with the coefficients completely. Here's my code:  \begin{equation} \begin{aligned} LNEP = &amp; -0.23LNEER &amp; +1.21LNCOST &amp; +1.50LNFD &amp; -1.03LNCP &amp; -9.44 \\ &amp; (0.12) &amp; (0.13) &amp; (0.27) &amp; (0.37) &amp; (1.33) \end{aligned} \end{equation}   And it looks like this:   Could somebody help me pls? Many thanks.

I need to add some more publications. I do not want to change the previous reference numbers, so I need to create new citations with difference reference numbering like [p1], [p2], etc. Can LaTeX do that?
