\begin_layout Section
Einleitung
\end_layout

\begin_layout Standard
Dieses Dokument ist eine Zusammenstellung und Erläuterung der wichtigsten
 LaTeX-Befehle für mathematische Zeichen und Konstruktionen.
 Die Erläuterungen sind speziell auf die Benutzung der Befehle mit LyX zugeschni
tten.
 Das setzt voraus, dass bereits das Kapitel 
\family typewriter
Mathematische
\family default
 
\family typewriter
Formeln
\family default
 des Benutzerhandbuchs gelesen worden ist.
\end_layout

\begin_layout Standard
Die meisten Zeichen und viele Konstruktionen sind auch über das Menü 
\family sans
Einfügen
\series bold
\SpecialChar \menuseparator

\series default
Mathe
\family default
 oder die 
\family sans
Mathe-Werkzeugleiste
\family default
 aufrufbar.
 Wer viele Formeln zu schreiben hat, wird jedoch feststellen, dass man mit
 den LaTeX-Befehlen viel schneller eine Formel setzen kann.
 Daher wird in diesem Handbuch der Fokus auf Befehle gesetzt wobei entsprechende
 Werkzeugleistenknöpfe, falls vorhanden, erwähnt werden.
\end_layout

\begin_layout Standard
Sofern nicht anders angegeben, sind Befehle nur in der Formel-Umgebung von
 LyX verfügbar.
 Um alle Befehle nutzen zu können, muss die Option 
\family sans
AMS-Mathe-Paket verwenden
\family default
 im Menü 
\family sans

\begin_layout Plain Layout
Formel ! abgesetzte
\end_layout

\end_inset

 zu erstellen, drückt man 
\family sans

\family default
.
\end_layout

\begin_layout Standard
Um eine abgesetzte Formel in eine eingebettete umzuwandeln, setzt man den
 Cursor in die Formel und drückt 
\family sans
Strg+Shift+M

\end_inset

Formelart ändern
\family default
.
 Auf die selbe Weise lässt sich eine eingebettete in eine abgesetzte Formel
 umwandeln.
\end_layout

\begin_layout Standard
Um Teile einer eingebetteten Formel in der Größe einer abgesetzten darzustellen,
 gibt man in die Formel den Befehl 
\series bold

 Es erscheint ein neues blaues Kästchen, in das dann der Formelteil eingegeben
 wird.
\end_layout

\begin_layout Standard
In einer Tabelle dürfen nur eingebettete Formeln verwendet werden.

Die 
\family sans
Mathe-Werkzeugleiste
\family default

 Wenn nun im Menü 
\family sans
Werkzeugleisten
\family default
 nochmal auf 
\begin_inset Quotes eld
\end_inset

Mathe
\begin_inset Quotes erd
\end_inset

 geklickt wird, wird die Werkzeugleiste nur angezeigt, wenn sich der Cursor
 in einer Formel befindet; diese Einstellung wird durch die Umbenennung
 des Menüeintrags von

Befehlsschema
\end_layout

\begin_layout Standard
Die meisten LaTeX-Befehle für mathematische Konstruktionen besitzen folgendes
 Schema:
\end_layout

\begin_layout Standard

\series bold

\backslash
Befehlsname[optionales
\series default
 
\series bold
Argument]{anzugebendes
\series default
 
\series bold
Argument}
\end_layout

\begin_layout Standard
Ein Befehl muss immer mit einem Backslash 
\begin_inset Quotes gld
\end_inset


\series bold

\backslash

\series default

\begin_inset Quotes grd
\end_inset

 beginnen.
 Möchte man ein optionales Argument nicht angeben, müssen auch die zugehörigen
 eckigen Klammern weggelassen werden.
 Die geschweiften Klammern werden in diesem Dokument als TeX-Klammern
\begin_inset Index idx
status collapsed

\begin_layout Plain Layout
T@TeX-Klammern
\end_layout

\end_inset

 bezeichnet.
 Hängt man in einer Formel an Befehlsnamen eine linke geschweifte Klammer
 an, erzeugt LyX automatisch eine TeX-Klammer.
 Ansonsten werden sie in Formeln mit dem Befehl 
\series bold

\backslash
{
\series default
 erzeugt.
 TeX-Klammern erscheinen in LyX rot, im Gegensatz zu normalen geschweiften
 Klammern, die blau erscheinen.
 Im TeX-Modus sind für TeX-Klammern keine Befehle notwendig.
 TeX-Klammern erscheinen nicht im Ausdruck.
\end_layout

\begin_layout Standard
Werden Befehle ohne Argumente, wie z.
\begin_inset space \thinspace{}
\end_inset

B.
 Symbolbefehle, im TeX-Modus eingegeben, muss auf den Befehl 
\emph on
immer
\emph default
 ein Leerzeichen folgen um ihn zu beenden.
 Dieses Leerzeichen erscheint nicht im Ausdruck.
 Soll das Leerzeichen auch im Ausdruck erscheinen, muss auf den Befehl im
 normalen Text ein geschütztes Leerzeichen folgen.
\end_layout

\begin_layout Standard
Ein geschütztes Leerzeichen gibt man mit 
\family sans
Strg+Leertaste
\family default
 ein.
\end_layout

\begin_layout Subsection*

Benötigt man Klammern, die sich überschneiden, muss man die in 
\begin_inset CommandInset ref
LatexCommand ref
reference "sec:Mehrzeilige-Formeln"

\end_inset

 beschriebenen mehrzeiligen Formeln verwenden:
\begin_inset Formula 
\begin{eqnarray*}
A & = & \underbrace{gggg+bbqq}_{r}+\: dddd\\
 &  & \hphantom{gggg+\:}\underbrace{\hphantom{bbqq+dddd}}_{s}
\end{eqnarray*}

\end_inset

In die erste Zeile wird die Formel zusammen mit der ersten Klammer eingegeben.
 Dabei ist es wichtig, dass vor dem ersten

 eingegeben wird, denn die nach dem

 In die zweite Zeile wird die zweite Klammer eingegeben.
 Da sie vor dem

 Dieser Leerraum wird benötigt, weil das 
\begin_inset Quotes gld
\end_inset

\end_inset

 in der Formel auch von Leerraum umgeben ist.
 Die Klammer wird unter den Befehl

\end_layout

Komplizierter wird es, wenn sich Klammern über und unter der Formel überschneide
n, wie in folgendem Beispiel:

\begin_inset Formula 
\begin{eqnarray*}

Die erste Formelzeile ist gleich der zweiten Zeile des vorigen Beispiels,
 mit dem Unterschied, dass sich die Klammer oben befindet.
 Die zweite Zeile enthält die Formel zusammen mit der zweiten Klammer.
 Damit sich zwischen oberer Klammer in der ersten Zeile und der Formel in
 der zweiten Zeile kein Leerraum befindet, muss der Zeilenabstand verändert
 werden.
 Aufgrund eines Fehlers in LyX ist dies nicht ohne Weiteres möglich

\begin_layout Standard
Bei einer Formel in einer Textzeile werden die Grenzen rechts neben den
 Operator gesetzt.
 In einer abgesetzten Formel werden, außer bei Integralen, die Grenzen über
 bzw.
\begin_inset space \space{}
\end_inset

unter den Operator gesetzt.
\end_layout

\begin_layout Standard
Um zu erzwingen, dass die Grenzen neben den Operator gesetzt werden, setzt
 man den Cursor direkt hinter den Operator und setzt über das Menü 
\family sans
Bearbeiten\SpecialChar \menuseparator
Mathe\SpecialChar \menuseparator
Art der Operatorgrenzen ändern
\family default
 die Grenzen auf 
\series bold
Eingebettet
\series default
 (Tastenkombination 
\family sans
Alt+M
\begin_inset space ~
\end_inset

L
\family default
).
 Dazu folgendes Beispiel:
\end_layout

\begin_layout Standard
Die normalen Grenzen sehen so aus:
\begin_inset Formula 
\[
\sum_{x=0}^{\infty}\frac{1}{x^{2}}
\]

\end_inset

So sieht die Formel aus, wenn man die Grenzen neben das Summenzeichen setzt:
\begin_inset Formula 
\[
\sum\nolimits _{x=0}^{\infty}\frac{1}{x^{2}}
\]

\end_inset

Bei Integralen werden mit Ausnahme von denen, die auf 
\series bold
op
\series default
 enden (
\series bold

\backslash
intop
\series default
, 
\series bold

\backslash
ointop
\series default
 usw.), die Grenzen standardmäßig neben den Operator gesetzt.
 Bei Mehrfachintegralen werden die Grenzen jedoch meistens unter den Operator
 gesetzt.
 Im folgenden Beispiel wurde die Grenze deswegen auf 
\series bold
Anzeige
\series default
 gesetzt und damit unter die Integrale geschrieben:
\begin_inset Formula 
\begin{equation}
\iiint\limits _{V}X\,\mathrm{d}V=U\label{eq:VolInt}
\end{equation}

\end_inset


\end_layout

\begin_layout Standard

\end{equation}

\end_inset

zu erstellen, muss man Folgendes tun:
\begin_inset Newline newline
\end_inset

Zuerst gibt man den Befehl 
\series bold

\backslash
sum
\series default
^
\series bold
n
\begin_inset space \textvisiblespace{}
\end_inset

_
\series default
 ein.
 Man befindet sich nun in einem blauen Kästchen unter dem Summenzeichen.
 In dieses gibt man den Befehl 
\series bold

\backslash
subarray
\begin_inset space \textvisiblespace{}
\end_inset


\series default
 ein.
 Das blaue Kästchen hat nun eine lila Umrandung und man kann jetzt mehrere
 Zeilen untereinander schreiben.
 Mit Eingabe des Zeilenumbruchs (
\family sans
Strg+Enter
\family default
) wird eine neue Zeile erstellt.
 Gibt man
\begin_inset Newline newline
\end_inset


\series bold
0<k<1000 Strg+Enter
\begin_inset Newline newline
\end_inset


\series default
ein, erscheint darunter ein Kästchen für die neue Zeile.
\end_layout

\begin_layout Standard
Die Ausrichtung der Zeilen kann mit der 
\family sans
Tabellen-Werkzeugleiste
\family default
 oder dem Menü 
\family sans
Bearbeiten\SpecialChar \menuseparator
Zeilen & Spalten
\family default
 auf links geändert werden.
 Um rechts ausgerichtete Zeilen zu erhalten, wird am Anfang der Zeile 
\series bold

\backslash
hfill
\begin_inset space \textvisiblespace{}
\end_inset


\series default
 eingegeben.

Der Befehl 
\series bold

\backslash
substack
\series default
 ist äquivalent zu 
\series bold

\backslash
subarray
\series default
, mit dem Unterschied dass die Zeilen immer zentriert ausgerichtet sind.
\end_layout

\begin_layout Standard
\begin_inset VSpace bigskip
\end_inset

Wie bei Formel 
\begin_inset CommandInset ref
LatexCommand eqref
reference "eq:substack"

\end_inset

 kann es vorkommen, dass sich neben dem Operator zu viel Leerraum befindet,
 denn das dem Operator folgende Zeichen wird neben die Grenzen gesetzt.
\end_layout

\begin_layout Standard
Um das zu verhindern, kann man folgendes Makro in den LaTeX-Vorspann einfügen:
\end_layout

\begin_layout Standard

\series bold

\backslash
def
\backslash
clap#1{
\backslash
hbox to 0pt{
\backslash
hss #1
\backslash
hss}}
\begin_inset Newline newline
\end_inset


\backslash
def
\backslash
mathclap {
\backslash
mathpalette 
\backslash
mathclapinternal}
\begin_inset Newline newline
\end_inset


\backslash
def
\backslash
mathclapinternal #1#2{
\backslash
clap{$
\backslash
mathsurround =0pt #1{#2}$}}
\end_layout

\begin_layout Standard
Dadurch wird der Befehl 
\series bold

\backslash
mathclap
\series default

\begin_inset Index idx
status collapsed

\begin_layout Plain Layout
Befehle ! M ! 
\backslash
mathclap
\end_layout

\end_inset

 definiert, der die Breite der Grenze auf 0
\begin_inset space \thinspace{}
\end_inset

pt setzt.
 Das Befehlsschema lautet
\end_layout

\begin_layout Standard

\series bold

\backslash
mathclap{Grenze}
\end_layout

\begin_layout Standard
wobei die Grenze auch aus mehreren Bedingungen bestehen kann.
\end_layout

\begin_layout Standard
Auf Formel 
\begin_inset CommandInset ref
LatexCommand eqref
reference "eq:substack"

\end_inset

 angewandt, gibt man also den Befehl
\end_layout

\begin_layout Standard

\series bold

\backslash

\backslash
mathclap{
\backslash
substack
\begin_inset space \textvisiblespace{}
\end_inset

0<k<1000 Strg+Enter
\end_layout

\begin_layout Standard
ein, um die untere Grenze zu erstellen.
 Der Summand befindet sich nun direkt hinter dem Summenzeichen:

\[

\begin_layout Plain Layout
Befehle ! S !

 Größe aller nachfolgenden Formel- und Textzeichen fest.
 Um wieder zur Ausgangsgröße zurückzukehren, gibt man nach der Formel im
 TeX-Modus den Befehl 
\series bold

\backslash

Es gibt eine weitere Möglichkeit die Schriftgröße zu ändern, die allerdings
 nur für Symbole oder Buchstaben im mathematischen Text funktioniert.
 Dazu wird einer der obigen Textgrößenbefehle im mathematischen Textmodus
 eingegeben.
 Alle diesem Befehl folgenden Zeichen bis zum Ende des mathematischen Textes
 oder bis zu einem anderen Größenbefehl haben dann die angegebene Größe.
 Dazu zwei Beispiele:

Dass die großen griechischen Buchstaben aufrecht erscheinen, ist einem Fehler
 geschuldet, der während der Entwicklung von TeX gemacht wurde.
 Um korrekte kursive Großbuchstaben zu erhalten, beginnt man einen Befehl
 mit 
\series bold
var
\series default
.
 So ergibt z.

 Zwischen Vorfaktor und Funktion fügt man einen kleinen Leerraum ein.

Eine Besonderheit stellt die Modulo-Funktion dar, denn es gibt sie in vier
 Varianten.
\end_layout

\begin_layout Standard
Die Varianten in einer abgesetzten Formel:
\begin_inset Formula 
\begin{align*}
\underline{\textrm{Befehl}\raisebox{-0.9mm}{}} &  & \underline{\textrm{Ergebnis}}\\
\mathrm{a\backslash mod\textrm{␣}b} &  & a\mod b\\
\mathrm{a\backslash pmod\textrm{␣}b} &  & a\pmod b\\
\mathrm{a\backslash bmod\textrm{␣}b} &  & a\bmod b\\
\mathrm{a\backslash pod\textrm{␣}b} &  & a\pod b
\end{align*}

\end_inset


\end_layout

\begin_layout Standard
In einer eingebetteten Formel wird bei allen Varianten vor den Funktionsnamen
 weniger Leerraum gesetzt.
 Standardmäßig beachten die Modulo-Funktionen nur das erste, folgende Zeichen.
 Um mehrere Zeichen zu verwenden, muss man sie in TeX-Klammern setzen:
\begin_inset Formula 
\begin{align*}
\underline{\textrm{Befehl}\raisebox{-0.9mm}{}} &  & \underline{\textrm{Ergebnis}}\\
\mathrm{a\backslash pod\textrm{␣}bcd} &  & a\pod bcd\\

\begin_layout Standard
Zähler gibt an, welche Nummerierung betroffen ist.

 Um diesen Problemen aus dem Weg zu gehen, gibt es in LyX die Möglichkeit
 Mathe-Makros statt den Befehl

newmacroname ist der voreingestellte Makroname, der auf etwas sinnvolles

 In das erste blaue Kästchen gibt man die gewünschte Formel ein.

 Argumentplatzhalter werden rot dargestellt.

 Optionale Argumente werden mit dem Werkzeugleistenknopf 
\begin_inset Graphics

 erstellt.
 Mit dem Werkzeugleistenknopf 
\begin_inset Graphics

\end_inset

 kann das erste nicht-optionale Argument in ein optionales verwandelt werden.
 Im zweiten Kästchen kann man definieren wie das Makro in LyX angezeigt
 werden soll.
 Normalerweise will man es so sehen, wie es definiert wurde, wozu man das
 Kästchen leer lässt.
 Hat man hingegen ein Makro erstellt, der auf dem Bildschirm viel Platz
 einnimmt, kann man in das Kästchen z.

 Für das Makro werden dann in LyX nur die Argumente mit dem davor stehenden
 Makronamen angezeigt, was für mehr Überblick im Dokument sorgt.
 Im Ausdruck erscheint die Formel so, wie sie im ersten Kästchen definiert

Das Erscheinungsbild von Makros in Formeln lässt sich außerdem für einzelne
 Makros ändern, indem man den Cursor in das Makro setzt und das Menü

\begin_layout Standard
Um ein Makro zu verwenden, gibt man in eine Formel den Makronamen als Befehl

\begin_layout Standard
Ein Mathe-Makro wird beim Exportieren des Dokuments intern in einen

\series default
-Befehl umgewandelt.
 Der

 Makros nur in Formeln verwenden kann, die sich im Dokument unterhalb der
 Makrodefinitionsbox befinden.
\end_layout

\begin_layout Standard
Mathe-Makros können auch direkt aus einem 
\series bold

 Bei dieser Methode muss man jedoch aufpassen, dass der

-Befehl richtig geschrieben wurde, ansonsten wird ein fehlerhaftes Makro
 erstellt, dass später LaTeX-Fehler hervorruft.
\end_layout

\begin_layout Standard
Mathe-Makros haben im Moment noch das Problem, dass weitere Formeln in einer
 Makrodefinition fehlerhaft behandelt werden.
 Dadurch kann das Beispiel

Das Paket

 sorgt dafür, dass die Beschriftungen in der ausgewählten Sprache erscheinen.
 Ehe man Beschriftungen ändern kann, muss es geladen werden.
 Außerdem wird

 von LyX automatisch nach dem LaTeX-Vorspann geladen.
 Das ruft aber keine Probleme hervor, solange im LaTeX-Vorspann die Dokumentspra
