Text Formatting ⇒ \subsubsection counter

[svend_tveskaeg]

Hi LaTeX friends.

I'm typing exercises using the \subsubsection command, e.g.,

Code: Select all

Code, edit and compile here:

1
2
3
\subsubsection{Exercise~1}
\label{exc:1}
This is exercise~\label{exc:1}.

Run LaTeX here

Typing this I get ``This is exercise x.x.1.'' instead of ``This is exercise 1.''

How do I get the latter of the two?

Thanks in advance!

You can define a new counter for your exercises

Code: Select all

Code, edit and compile here:

1
2
3
4
5
6
7
8
9
10
11
12
13
14
\documentclass{article}
\begin{document}
\newcounter{exer}
\subsubsection{Exercise~1}\label{ex:1}
\stepcounter{exer}
This is subsubsection~\ref{ex:1} but exercise~\arabic{exer} within
\subsubsection{Exercise~2}\label{ex:2}
\stepcounter{exer}
This is subsubsection~\ref{ex:2} but exercise~\arabic{exer} within
\end{document}

Thank you, very much!

Hey, check this idea out:

Code: Select all

1
2
{\renewcommand{\thesubsubsection}{\arabic{subsubsection}.}\thesubsubsection}
\thesubsubsection

Its better in the sense you won't have to create any new counters!

[svend_tveskaeg]

Thanks to both of you!


Another problem:
Can someone tell me why the attached file won't compile? (I'm using TeX Live 2009 on an Ubuntu 9.10 machine.)

I have tried to follow the example on page 151 in The LaTeX Companion, 2nd Edition.

[karlisrepsons]

Well, to me there were at least two problems:
1. unicode input;
2. somewhat crazy use of list environment.

Sorry if you don't have XeTeX, but I wrote it for that + you'll have to figure out, if you really need that kind of environment as you tried to. Look:

\begin{document}
\tableofcontents
\section{Du får oplyst at cirklens omkreds kan beregnes ved formlen}
\begin{equation}
 \label{omkreds1}
  O = \pi \cdot d = 3{,}14 \cdot d,
\end{equation}
hvor $\pi$ \emph{altid} har værdien $3{,}14$. Din opgave er nu at
udregne cirlens omkreds $O$, når det oplyses at diametren er $d = 3$.
\label{opg:1}
\section{En anden formel for cirklen omkreds er}
\begin{equation}
 \label{omkreds2}
  O = 2 \cdot \pi \cdot r.
\end{equation}
Nu skal du måle $r$ på figuren [som ikke er indtegnet i opgaveformuleringen
endnu] og så bruge formel~\eqref{omkreds2} til at beregne omkredsen
$O$.\label{opg:2}
\end{document}

Seemed ok to me, but I'm Latvian and not you

[svend_tveskaeg]

(1) My enconding is [update: not] fine. [Update: You are right but it is now fixed.]
(2) I would like an environment like the one I've tried to put together in the attached file. [Update: I have figured out the problems.]

[Update: Thanks to you all!]
