Examples using the giac CAS inside a L^AT_EX file.

This L^AT_EX source will output an interactive HTML file if you compile with hevea (tested with hevea 2.23), where interactive computations are done with the computer algebra system Giac. You must first enter the command \input{giac.tex} in the preamble and add one of the commands \loadgiacjs or \loadgiacjsonline somewhere in the document: the difference is that the javascript kernel giac.js will be found on the hard disk (assuming that Giac/Xcas is installed on the target computer) or downloaded from Internet.

Inline command example with text or plot output \giacinput, example: \giacinput{factor(x^4-1)} :
factor(x^4-1) ok

Same command with optional style argument
\giacinput[style="width:200px;height:20px;font-size:large"]{plot(sin(x))}
plot(sin(x)) ok

A button with a command applied on the field entry with \giaccmd, example \giaccmd{factor}{x^4-1} :
x^4-1 factor

with optional style argument x^4-1 factor

For a program or multi-line commands
\begin{giacprog}...\end{giacprog}, example homemade absolute value

f(x):={
  local y;
  if x<0 then y:=-x; else y=x; fi;
  return y;
}

ok

Inline command with mathml output \giacinputmath{} or \giaccmdmath{}{} :
factor(x^10-1) ok

factor(x^10-1) ok

x^4-1 factor

x^4-1 factor

Outline command with mathml output \giacinputbigmath{} or \giaccmdbigmath{}{} :
