<tmdoc-title|Incorporating mathematical formulas into documents>
|
||
|
|
|
||
|
|
<TeXmacs> provides three main ways in order to enter a mathematical
|
||
|
|
formulas into the main text:
|
||
|
|
|
||
|
|
<\description>
|
||
|
|
<item*|<menu|Insert|Mathematics|Formula> or <key|$>>
|
||
|
|
|
||
|
|
This entry corresponds to small <em|inline formulas> like
|
||
|
|
<math|a<rsup|2>+b<rsup|2>=c<rsup|2>> inside a textual paragraph. Note
|
||
|
|
that formulas are typeset specially so they do not take too much vertical
|
||
|
|
space. For example, limits are always displayed on the left. Limits can
|
||
|
|
be displayed below in formulas with <menu|Format|Formula style|on>. In
|
||
|
|
formulas, formula style is off by default.
|
||
|
|
|
||
|
|
<item*|<menu|Insert|Mathematics|Equation> or <shortcut|(make-equation*)>>
|
||
|
|
|
||
|
|
This entry is used for entering bigger <em|displayed equations>, like
|
||
|
|
|
||
|
|
<\equation*>
|
||
|
|
x<rsup|n>+y<rsup|n>=z<rsup|n>,
|
||
|
|
</equation*>
|
||
|
|
|
||
|
|
which are typeset in a paragraph of their own. You may use the shortcut
|
||
|
|
<shortcut|(numbered-toggle (focus-tree))> in order to give the equation a
|
||
|
|
number (or to remove the number of an equation). Also,
|
||
|
|
<shortcut|(variant-circulate (focus-tree) #t)> allows you to switch
|
||
|
|
between inline formulas and displayed equations.
|
||
|
|
|
||
|
|
<item*|<menu|Insert|Mathematics|Equations> or
|
||
|
|
<shortcut|(make-eqnarray*)>>
|
||
|
|
|
||
|
|
This entry allows you to create an <markup|eqnarray*>, a three columns
|
||
|
|
wide table-like environment (see <hlink|creating
|
||
|
|
tables|../table/man-create-table.en.tm>). This environment is typically
|
||
|
|
used for lists of multiple relations like
|
||
|
|
|
||
|
|
<\eqnarray*>
|
||
|
|
<tformat|<table|<row|<cell|x+0>|<cell|=>|<cell|x>>|<row|<cell|x+<around|(|\<um\>x|)>>|<cell|=>|<cell|0>>|<row|<cell|x+y>|<cell|=>|<cell|y+x>>|<row|<cell|<around|(|x+y|)>+z>|<cell|=>|<cell|x+<around|(|y+z|)>>>>>
|
||
|
|
</eqnarray*>
|
||
|
|
|
||
|
|
The first column is centered to the right, the second one at the middle
|
||
|
|
and the last one at the left. An other typical use of the
|
||
|
|
<markup|eqnarray*> environment is a step by step computation
|
||
|
|
|
||
|
|
<\eqnarray*>
|
||
|
|
<tformat|<table|<row|<cell|<around*|(|\<mathe\><rsup|sin x>+sin
|
||
|
|
\<mathe\><rsup|x>|)><rprime|'>>|<cell|=>|<cell|<around*|(|\<mathe\><rsup|sin
|
||
|
|
x>|)><rprime|'>+<around*|(|sin \<mathe\><rsup|x>|)><rprime|'>>>|<row|<cell|>|<cell|=>|<cell|<around|(|sin
|
||
|
|
x|)><rprime|'>*\<mathe\><rsup|sin x>+<around*|(|\<mathe\><rsup|x>|)><rprime|'>*sin
|
||
|
|
\<mathe\><rsup|x>>>|<row|<cell|>|<cell|=>|<cell|\<mathe\><rsup|sin
|
||
|
|
x>*cos x+\<mathe\><rsup|x>*sin \<mathe\><rsup|x>,>>>>
|
||
|
|
</eqnarray*>
|
||
|
|
|
||
|
|
in which many entries of the left column are left open.
