Using Yacas sessions inside <TeXmacs>
</expand>
As its name indicates, <name|Yacas> is Yet Another CAS, which can be
downloaded from
<\verbatim>
\ \ \ \ http://www.xs4all.nl/~apinkus/yacas.html
</verbatim>
You may start a <name|Yacas> session using
<apply|menu|Insert|Session|Yacas>. Here follows a short demo:
<\session|yacas|defau>
<\output>
\;
</output>
<\input|yacas] >
f(x):= x+Sin(x);
</input>
<\output>
<\with|mode|math>
<with|math font family|rm|True>
</with>
</output>
<\input|yacas] >
D(x) f(x);
</input>
<\output>
<\with|mode|math>
cos x+1
</with>
</output>
<\input|yacas] >
Integrate(x,0,Pi) f(x);
</input>
<\output>
<\with|mode|math>
<frac|\<pi\><rsup|2>|2>+2
</with>
</output>
<\input|yacas] >
GnuPlot(-10,10,80,f(x));
</input>
<\output>
<\with|mode|math>
<with|math font family|rm|True>
</with>
</output>
<\input|yacas] >
\;
</input>
</session>
The produced graph in the last command is shown in another window. Using
the ``snapshot'' of the <name|Gimp> you can save the graph as an image and
embed into the worksheet using <apply|menu|Insert|Image>:
