DESCRIPTION

giac is an advanced symbolic and numeric calculator. The console interface is named icas or equivalently giac . The corresponding GUI program is called xcas .

These programs have extensive documentation. The GIAC/XCAS manual is available in Info format by invoking ‘info giac‘, and in HTML and DVI format in /usr/share/giac/doc . One can also obtain some help about a keyword like this, from inside the program:

0>> ?gcd
Returns the greatest common divisor of 2 polynomials of several variables
or of 2 integers or of 2 rationals.
(Intg(a) or Poly),(Intg(b) or Poly)
gcd(45,75); gcd(15/7,50/9); gcd(xˆ2-2*x+1,xˆ3-1); gcd(tˆ2-2*t+1,tˆ2+t-2);
gcd((xˆ2-1)*(yˆ2-1)*zˆ2,xˆ3*yˆ3*z+(-(yˆ3))*z+xˆ3*z-z)
lcm,euler,modgcd,ezgcd,psrgcd,heugcd,Gcd

The equivalent output may be retrieved by invoking (e.g.) ‘cas_help gcd‘.
