<para>&kformula; is used to write formulas. It doesn't evaluate
|
||
|
|
anything. All it does is print them.</para>
|
||
|
|
<para>&kformula; was designed for your editing pleasure. It makes it
|
||
|
|
delightful to enter Greek letters, fractions and all the stuff that
|
||
|
|
makes a formula look like a formula.</para>
|
||
|
|
<para>But most of the time you won't want to use &kformula; itself.
|
||
|
|
Instead you might choose to use it from within &kword; or any other
|
||
|
|
&koffice; application. That is &kformula; is not a useful application
|
||
|
|
on its own but an extension to all the other &koffice; applications
|
||
|
|
you've fallen in love with.</para>
|
||
|
|
|
||
|
|
<para>Where ever &kformula; gets embedded, it will
|
||
|
|
behave the same.</para>

|
<para>A new (empty) &kformula; document looks like a small blue square.
|
||
|
|
This square stands for the central idea of &kformula;. It represents an
|
||
|
|
empty list. The idea of &kformula; is to have different elements
|
||
|
|
arranged in lists. An element in this respect might be a single char
|
||
|
|
or a root symbol or something like that. The lists are put together so
|
||
|
|
that they form a formula. That is there are lists for indexes, lower
|
||
|
|
and upper bounds and so on. And of course there is the main
|
||
|
|
list, which we've already seen.</para>
|
||
|
|
|
||
|
|
<para>Writing a formula means to fill the empty list with letters,
|
||
|
|
figures and mathematical symbols. That is straightforward: use your
|
||
|
|
keyboard. As soon as you type something the <quote>empty</quote>
|
||
|
|
symbol will vanish and you will see whatever you have inserted
|
||
|
|
instead. New characters are always put at the current cursor
|
||
|
|
position.</para>
|
||
|
|
|
||
|
|
<para>There is a toolbar called <guilabel>Add</guilabel> that allows
|
||
|
|
you to create more complex elements. There are indices, fractions,
|
||
|
|
roots and matrices to name a few. All these elements
|
||
|
|
consist of at least one list, you can move the cursor into and insert
|
||
|
|
new items.</para>

<para> Below is a typical formula entry in &kformula;. To enter the partial
|
||
|
|
derivatives and Greek letters click on the symbol combo box, on the
|
||
|
|
right, and select the appropriate symbol. The symbol combo box, in the figure
|
||
|
|
below, has the word
|
||
|
|
<quote>Cap</quote> on it. Click on the return key symbol to the right of it,
|
||
|
|
to enter a symbol.</para>

<title>Name insertion</title>
|
||
|
|
<para>
|
||
|
|
A special feature is the name insertion. The blue square you
|
||
|
|
type into is actual a list. Furthermore, that list can contain other
|
||
|
|
lists. When you type a backslash (<literal>\</literal>) you get a new
|
||
|
|
empty list right away. But this one is special. It uses a different
|
||
|
|
font and is meant to insert things like function names. There is,
|
||
|
|
however, a second idea here. Your keyboard only has a limited number of keys.
|
||
|
|
The wealth of mathematical symbols on the other side is overwhelming. To get one
|
||
|
|
of those you can type its name and press the space bar afterwards. The name you
|
||
|
|
typed will be replaced by the symbol then. In this context, the
|
||
|
|
<keycap>Space</keycap> bar means <quote>get out of here</quote>, that
|
||
|
|
is move the cursor to the containing list. The cursor will be
|
||
|
|
positioned at the end of what you just entered but will also enclose part of the original
|
||
|
|
formula, after pressing the space bar.
|
||
|
|
</para>
|
||
|
|
|
||
|
|
<para>Another thing you might want to insert are spaces. We all know,
|
||
|
|
printing formulae is all about the right spacing. And you can do just
|
||
|
|
that using a <quote>name list</quote>.</para>
|
||
|
|
<para>
|
||
|
|
Inside the blue square do: <userinput><keycombo
|
||
|
|
action="seq"><keycap>\</keycap><keycap>,</keycap><keycap>SPACE</keycap></keycombo></userinput> to get a small space.
|
||
|

</para>
|
||
|

|
||
|
|
Do: <userinput><keycombo
|
||
|

action="seq"><keycap>\</keycap><keycap><</keycap><keycap>Space</keycap></keycombo></userinput> to get a medium space.
|
||

|
|
Do: <userinput><keycombo

<para>

a quadruple wide space.

the path integral about a closed contour. Below is the result of

<para>Here <literal>dydx[1]</literal> is the first order derivative and <literal>dydx[2]</literal> is the second order

<para>
|

|
The upper or lower index can be positioned by highlighting the desired
|
||
|
|
text. In this example, an arrow is needed above the P, in dP. Using <keycombo
|
||
|
|
action="simul">&Ctrl;<keycap>U</keycap></keycombo> places the desired vector
|
||
|
|
symbol in the wrong place; namely above the <quote>d</quote>.
