NAME
giac - computer algebra system
SYNOPSIS
giac [options] files
icas [options] files
xcas files
DESCRIPTION
giac is an advanced symbolic and numeric calculator. The console inter-
face 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(x^2-2*x+1,x^3-1);
gcd(t^2-2*t+1,t^2+t-2);
gcd((x^2-1)*(y^2-1)*z^2,x^3*y^3*z+(-(y^3))*z+x^3*z-z)
lcm,euler,modgcd,ezgcd,psrgcd,heugcd,Gcd
The equivalent output may be retrieved by invoking (e.g.) `cas_help
gcd`.
