π¦ DESCRIPTION π¦
So here's the tea: this right here is the help engine of the symbolic and numeric calculator giac, written by Bernard Parisse π. It ships in a few different languages, which is exactly why you've got all those variants in the synopsis β the help comes in different flavors, and honestly? iconic. no cap.
π EXAMPLE π
Type this bad boy in:
cas_help gcd
and the help for gcd shows up looking like this, verbatim:
Help for gcd:
gcd((Intg(a) or Poly),(Intg(b) or Poly))
Returns the greatest common divisor of 2 polynomials of several
variables or of 2 integers or of 2 rationals.
See also: 1/ lcm 2/ euler 2/ modgcd 3/ ezgcd 4/ psrgcd 5/ heugcd
6/ Gcd
Ex1:gcd(45,75)
Ex2:gcd(15/7,50/9)
Ex3:gcd(x^2-2*x+1,x^3-1)
Ex4:gcd(t^2-2*t+1,t^2+t-2)
Ex5:gcd((x^2-1)*(y^2-1)*z^2,x^3*y^3*z+(-(y^3))*z+x^3*z-z)
it's giving extremely thorough, and we love that for it π«Ά
