\begin_layout Section
Introduction
\end_layout
\begin_layout Standard
This document explains LyX's math features and is furthermore a collection
of LaTeX-commands used for mathematical characters and constructs.
The explanations are designed for the usage of commands.
It is therefore required that you have read the section
\family typewriter
Mathematical
\begin_inset space ~
\end_inset
Formulas
\family default
of the User's Guide.
\end_layout
\begin_layout Standard
Most of the characters and many constructs explained in this manual are
also accessible via the menu
\family sans
Insert
\series bold
\SpecialChar \menuseparator
\series default
Math
\family default
, or the
\family sans
math
\family default
\series bold
\family sans
\series default
toolbar
\family default
.
But everybody who has to write lots of formulas will notice that it is
much faster to use commands instead of the math toolbar.
Therefore this manual is focused on commands but also mentions the correspondin
g toolbar buttons when available.
\end_layout
\begin_layout Standard
If not specially mentioned the commands are only available within formulas.
To be able to use all commands explained in this document, the option
\family sans
Use AMS math package
\family default
must be used in the document settings (menu

\begin_layout Standard
To create an inline formula

\end_inset
To create a display style formula
\begin_inset Index idx

that will appear bigger and in an own paragraph, use one of these shortcuts:
\begin_inset Info

\end_layout
\begin_layout Standard
To change a display style formula to an inline formula, set the cursor into
the formula and use one of the shortcuts

Then a new blue box appears in which the desired formula part is inserted.
\end_layout
\begin_layout Standard
Only inline formulas are allowed inside tables.

other formula parts that appear blue.
In the output mathematical text is set upright, in contrary to other formula
parts.
\end_layout
\begin_layout Subsection*
Command Scheme
\end_layout
\begin_layout Standard
Most of the LaTeX-commands for math constructs have the following scheme:
\end_layout
\begin_layout Standard
\series bold
\backslash
commandname[optional
\series default
\series bold
argument]{required
\series default
\series bold
argument}
\end_layout
\begin_layout Standard
A command starts always with a backslash
\begin_inset Quotes gld
\end_inset
\series bold
\backslash
\series default
\begin_inset Quotes grd
\end_inset
.
To omit optional arguments, also omit the associated brackets.
The braces around the required arguments are named in this document as
TeX-braces
\begin_inset Index idx
status collapsed
\begin_layout Plain Layout
T@TeX-braces
\end_layout
\end_inset
.
If you add in a formula a left brace to a command name, LyX creates automatical
ly a TeX-brace.
In all other cases TeX-braces are created in formulas with the command
\series bold
\backslash
{
\series default
.
TeX-braces appear red in LyX, in contrary to normal braces that appear
blue.
In TeX-mode no command is needed to get TeX-braces.
TeX-braces don't appear in the output.
\end_layout
\begin_layout Standard
When commands without arguments, like commands for symbols are entered in
TeX-mode, a space character must
\emph on
always
\emph default
be behind the command to end it.
This space doesn't appear in the output.
When the space should appear in the output, the space must be followed
by a protected space in normal text.
\end_layout
\begin_layout Standard
A protected space is inserted with
\begin_inset Info
type "shortcut"
arg "space-insert protected"

\begin_layout Standard
\begin_inset VSpace bigskip
\end_inset
When brackets are needed that overlap each other, multiline formulas, as
described in
\begin_inset CommandInset ref
LatexCommand ref
reference "sec:Multiline-Formulas"
\end_inset
, must be used:
\begin_inset Formula
\begin{eqnarray*}
A & = & \underbrace{gggg+bbqq}_{r}+\: dddd\\
& & \hphantom{gggg+\:}\underbrace{\hphantom{bbqq+dddd}}_{s}
\end{eqnarray*}
\end_inset
In the first row the formula is inserted together with the first brace.
It is hereby important that the space command
\begin_inset Foot
status collapsed
\begin_layout Plain Layout
Space commands are explained in
\begin_inset CommandInset ref
LatexCommand ref
reference "sub:Predefined-Space"
\end_inset
.
\end_layout
\end_inset
\series bold
\backslash
:
\series default
is inserted before the first
\begin_inset Formula $d$
\end_inset
, because the brace that ends behind the
\begin_inset Formula $q$
\end_inset
prevents that the following
\begin_inset Quotes eld
\end_inset
+
\begin_inset Quotes erd
\end_inset
is surrounded by space.
\begin_inset Foot
status collapsed
\begin_layout Plain Layout
because a bracket is not handled as character, see
\begin_inset CommandInset ref
LatexCommand ref
reference "sub:Binary-Operators"
\end_inset
\end_layout
\end_inset
In the second row the second brace is inserted.
As it should begin before the
\begin_inset Formula $b$
\end_inset
, first the command
\series bold
\backslash
hphantom{gggg+
\backslash
:}
\series default
is inserted.

\series bold
\backslash
hphantom
\series default
see
\begin_inset CommandInset ref
LatexCommand ref
reference "sub:Placeholders"
\end_inset
\end_layout
\end_inset
This space is needed because the
\begin_inset Quotes eld
\end_inset
+
\begin_inset Quotes erd
\end_inset
is also surrounded by space in the formula.
The brace is placed under the command
\series bold
\backslash
hphantom{bbqq+dddd}
\series default
.
\end_layout
\begin_layout Standard
It gets more complicated when brackets overlap each other, like in the following
example:
\begin_inset ERT
status collapsed
\begin_layout Plain Layout
\backslash
setlength{
\backslash
jot}{-6pt}
\end_layout
\end_inset
\begin_inset Formula
\begin{eqnarray*}
& & \hphantom{gggg+\:}\overbrace{\hphantom{bbqq+dddd}}^{s}\\
A & = & \underbrace{gggg+bbqq}_{r}+\: dddd
\end{eqnarray*}
\end_inset
\begin_inset ERT
status collapsed
\begin_layout Plain Layout
\backslash
setlength{
\backslash
jot}{3pt}
\end_layout
\end_inset
The first formula row is the same as the second row of the previous example,
with the difference that the brace is above.
The second row contains the formula together with the second brace.
To avoid that there is space between the upper brace in the first row and
the formula, the row spacing need to be reduced.
This is not easily possible due to a bug in LyX
\begin_inset Foot

\begin_layout Plain Layout
\begin_inset CommandInset href
LatexCommand href
name "LyX-bug #1505"
target "http://www.lyx.org/trac/ticket/1505"

\end_layout
\end_inset
.
As solution for the problem, the global formula row separation
\series bold
\backslash
jot
\series default
\begin_inset Index idx
status collapsed
\begin_layout Plain Layout
Commands ! J !
\backslash

\end_layout
\end_inset

\begin_inset space \thinspace{}
\end_inset

\series bold
\backslash
setlength{
\backslash
jot}{-6pt}
\series default
in TeX-mode.
\series bold
\backslash
jot
\series default
is set back after the formula to the standard value of 3
\begin_inset space \thinspace{}
\end_inset
pt using the same command.

You can directly insert accents like é to formulas.
LyX will transform them to the corresponding accent command.
For umlauts
\begin_inset Index idx

\begin_layout Plain Layout
Umlauts
\end_layout

it is better to insert a quotation mark before the vowel.
These two characters are then treated by LaTeX as

character when the formula part with the umlaut is marked as German.

Another advantage to
\series bold

\series default
is that umlauts can directly be converted to mathematical text because
the accent commands above are
\emph on
not allowed
\emph default
\emph on
in mathematical text
\emph default
.
To convert an accented character to mathematical text, only the character
under the accent may be converted.
This applies also for all other conversions, e.
\begin_inset space \thinspace{}
\end_inset
g.
\begin_inset space \space{}
\end_inset
to italic or bold.

Instead of

also the color space

\series bold

denotes
\series bold

\begin_layout Standard
The operators are called big because they are bigger than the sometimes
equal looking binary operators.
All big operators can have limits as described in the next subsection.
\end_layout
\begin_layout Standard
For all integral operators there is a second version available, ending on
\series bold
op
\series default
:
\series bold
\backslash

,
\series bold
\backslash

etc..
These operators are different from
\series bold

etc.
\begin_inset space \space{}

\begin_layout Subsubsection*
Advice for Integrals
\end_layout
\begin_layout Standard
The letter
\emph on
d
\emph default
in an integral is an operator, that therefore has to be set upright.
This is done by highlighting the
\emph on
d
\emph default
and using the keyboard shortcut
\begin_inset Info
type "shortcut"
arg "font-roman"
\end_inset

\end_inset
\end_layout
\end_inset
.
Finally the smallest space is inserted before the
\emph on
d
\emph default
, as this is usual for operators.
An example:

\begin_layout Standard
Limits of inline formulas are set right beside the operator.
Limits in displayed formulas are set above or below the operator, except
for integral limits.
\end_layout
\begin_layout Standard
To force that the limits are set beside the operator, the cursor is set
directly behind the operator and the limits type is changed with the menu
\family sans
Edit\SpecialChar \menuseparator
Math\SpecialChar \menuseparator
Change Limits Type
\family default
to
\family sans
\series bold
Inline
\family default
\series default
(shortcut
\begin_inset Info
type "shortcut"
arg "math-limits"
\end_inset
).
An example:
\end_layout
\begin_layout Standard
The default limits type is this:
\begin_inset Formula
\[
\sum_{x=0}^{\infty}\frac{1}{x^{2}}
\]
\end_inset
This is how it looks when the limits type was changed to
\family sans
\series bold
Inline
\family default
\series default
:
\begin_inset Formula
\[
\sum\nolimits _{x=0}^{\infty}\frac{1}{x^{2}}
\]
\end_inset
For integrals, except those ending with
\series bold
op
\series default
like
\series bold
\backslash
intop
\series default
,
\series bold
\backslash
ointop
\series default
etc., the limits are by default set beside the operator.
But for multiple integrals the limits are often set below the operator.
In the following example the limits type was therefore set to
\series bold
Display
\series default
and so set below the integrals:
\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
\begin_inset VSpace medskip

\end_layout
\begin_layout Standard
The size produced by the commands depends on the document font size, that
corresponds with the command
\series bold
\backslash
normalsize
\series default
.
The other commands produce smaller or larger sizes than
\series bold
\backslash
normalsize
\series default
.
The font size can however not exceed a certain value.
Is for example the document font size 12
\begin_inset space \thinspace{}
\end_inset
pt, the command
\series bold
\backslash
Huge
\series default
switches to the same size as
\series bold
\backslash
huge
\series default
.
\end_layout
\begin_layout Standard
A size command is inserted in TeX-mode before the formula and sets the size
for all following formula and text characters.
To switch back to the initial size, the command
\series bold
\backslash
normalsize
\series default
is inserted behind the formula in TeX-mode.

That the big Greek letters appear upright is caused by a design bug when
TeX was developed.
To get correct italic big letters, begin every command with
\series bold
var
\series default
.
For example the command
\series bold
\backslash
varGamma
\series default
produces
\begin_inset Formula $\varGamma$
\end_inset
.
Another way is to load the package

To use a function that is not predefined, like for example the sign function
sgn(x), there are two possibilities:
\end_layout
\begin_layout Itemize
Define the function by inserting the following line to the LaTeX-preamble

Now the new defined function can be called with the command
\series bold

sgn
\series default
.
\end_layout
\begin_layout Itemize
Write the formula as usual, mark the formula name, in our example the letters
\emph on
sgn
\emph default
, and change it to mathematical text.
At last a space is inserted between prefactor and function.
\end_layout

The minus sign at the beginning of the second line does normally not appear

User-defined commands are especially convenient for complex expressions.
When you are for example dealing in a document with quadratic equations,
the same solution type occurs several times.
The general form of a quadratic equation is
\begin_inset Formula
\[
0=\lambda^{2}+p\lambda+q
\]
\end_inset
The general form of the solution is
\begin_inset Formula
\[
\lambda_{1,2}=-\frac{p}{2}\pm\sqrt{\frac{p²}{4}-q}
\]

\end_inset
and
\begin_inset Formula $q$
\end_inset
need to be specified and the index of

The definition of the new command is unintuitive because one has to know
the schemes of all used LaTeX commands, e.
\begin_inset space \thinspace{}
\end_inset
g.
\begin_inset space \space{}
\end_inset
that a fraction is inserted in LaTeX as
\series bold
\backslash
frac{numerator}{denominator}
\series default
.
Furthermore one can easily forget a brace in the definition and cannot
see in LyX what the new command is doing.
To avoid these problems LyX offers the possibility to use math macros instead
of the command
\series bold
\backslash
newcommand
\series default

or the toolbar button
\begin_inset Graphics

\end_inset
\backslash
newmacroname is the default name of the macro that should be changed to
something sensible.
The wanted formula is inserted in the first blue box.
An argument placeholder is inserted with the command
\series bold
\backslash
#argumentnumber
\series default
, e.
\begin_inset space \thinspace{}
\end_inset
g
\begin_inset space \space{}
\end_inset
\series bold

or by using the macro toolbar button
\begin_inset Graphics
filename ../images/math-macro-add-param.png
scale 85
\end_inset
.
Argument placeholders are displayed red.
Maximum 9 arguments are possible.
Optional arguments are created with the toolbar button
\begin_inset Graphics
filename ../images/math-macro-add-optional-param.png
scale 85
\end_inset
.
The first non-optional argument can be transformed to an optional one with
the toolbar button
\begin_inset Graphics
filename ../images/math-macro-make-optional.png
scale 85
\end_inset
.
In the second blue box the appearance of the macro in LyX can be defined.
Normally you want to see it as it is defined, so the box is kept empty.
But when you have created a macro that needs lot of space on the screen,
you can insert in the box for example
\begin_inset Newline newline
\end_inset
\series bold
qG:
\backslash
#1
\series default
\series bold
,
\series default
\series bold
\backslash

\series bold

\series default
\series bold
\backslash
#3,
\backslash

\begin_inset Newline newline
\end_inset
\series default
For the macro only the arguments with the macro name in front of them will
then be displayed in LyX, leading to a better overview.
The formula appears in the output as defined in the first box.
\begin_inset Newline newline
\end_inset
The appearance of macros in formulas can furthermore be changed for single
macros by setting the cursor in the macro and using the menu

\begin_layout Standard
To use a macro, the macro name is inserted as command to a formula, in our
case
\series bold
\backslash
qG
\series default
.
Our macro looks in LyX like this:
\begin_inset Newline newline
\end_inset
\begin_inset space \hspace*{\fill}
\end_inset
\begin_inset Graphics
filename clipart/macrouse.png
\end_inset
\begin_inset space \hspace*{\fill}
\end_inset
\begin_inset Newline newline
\end_inset
Here is our macro example with the arguments
\begin_inset Formula $x$
\end_inset
,
\begin_inset Formula $\ln(x)$
\end_inset
and
\begin_inset Formula $B$
\end_inset
:
\end_layout
\begin_layout Standard
\begin_inset Formula
\[
\qG x{\ln(x)}B

\begin_layout Standard
LyX offers in the menu
\family sans
Tools\SpecialChar \menuseparator
Preferences\SpecialChar \menuseparator
Editing\SpecialChar \menuseparator
Control
\family default
different styles to edit macros.
To find the style that suits you the most, choose a style and set the cursor
in a macro formula to see the difference.
\end_layout
\begin_layout Standard
A math macro is transformed internally to a
\series bold
\backslash
newcommand
\series default
command when exporting the document.
The created
\series bold
\backslash
newcommand
\series default
command is not placed in the LaTeX-preamble, therefore macros can only
be used in formulas that are in the document below the macro definition
box.
\end_layout
\begin_layout Standard
Math macros can also be directly be created from a
\series bold
\backslash
newcommand
\series default
command.
When writing for example the command
\series bold
\begin_inset Newline newline
\end_inset
\backslash
newcommand{
\backslash
larrow}[2]{
\backslash
xleftarrow[#2]{#1}}
\begin_inset Newline newline
\end_inset
\series default
in LyX as normal text, highlighting it completely and using then the shortcut
\family sans
Ctrl+M
\family default
, the command will be transformed to a math macro.
Using this method you need to be careful that the
\series bold
\backslash
newcommand
\series default
command is typed correctly, otherwise you get a faulty macro leading to
LaTeX errors.
\end_layout
\begin_layout Standard
Math macros currently yet have the problem that further formulas in macro
definitions are handled wrongly.
Therefore the example
\series bold
\backslash
fb
\series default
from
\begin_inset CommandInset ref
LatexCommand ref
reference "sub:The-Command-newcommand"
\end_inset
cannot be created as macro.
\end_layout
\begin_layout Standard
When the cursor is in a macro definition box, you will see the macro toolbar
in LyX:

\begin_layout Standard
Negative numbers often look ugly in formulas because the minus sign before
the number is set with the same length as the minus operator sign.
When writing the negative number in normal text, the minus sign appears
correctly.
\end_layout
\begin_layout Standard
Thus, the problem disappears when converting the minus sign to mathematical
text.

The character encoding (menu
\family sans
Document\SpecialChar \menuseparator

When the key for the character '·' is pressed, internally the command
\series bold

is used.
But this command is not available in a formula so that you would get LaTeX-erro
rs.
With the changed encoding the right command is chosen automatically, depending
on if the character was inserted into a formula or not.
\end_layout
\begin_layout Standard
The encoding of several characters is saved in definition files.
Fore example the encoding
\series bold
