Functions and commands
Returns the list of roots and poles of a rational polynomial.
Each root or pole is followed by its multiplicity.
froot(RatPoly)
Returns the numerical solution of an equation or a system of
equations. With the optional third argument you can specify
a guess for the solution or an interval within which it is
expected that the solution will occur. With the optional fourth
argument you can name the iterative algorithm to be used by
the solver.
fsolve(Expr,Var,[Guess or Interval],[Method])
Returns the derivative function of a function.
function_diff(Fnc)
Using the Gauss algorithm, returns the quadratic form of an
expression written as a sum or difference of squares of the
given in VectVar.
gauss(Expr,VectVar)
Returns the color of the pixel G with coordinates x,y.
GETPIX_P([G], xposition, yposition)
G can be any of the graphics and is optional. The default is
G0, the current graphic.
Creates a Galois Field of characteristic p with p^n elements.
GF(Intg(p),Intg(n))
For a basis B of a vector subspace, and a function Sp that
defines a scalar product on this vector subspace, returns an
orthonormal basis for Sp.
gramschmidt(Basis(B),ScalarProd(Sp))
Used with display to specify the color of the geometrical
object to be displayed.
Draws a half-cone with vertex A, direction v, half angle t and,
if applicable, height h.
half_cone(Pnt(A),Vect(v),Real(t),[Real(h)])
Draws the half-line AB with A as the origin.
half_line((Pnt or Cplx(A)),(Pnt or Cplx(B)))
Returns an expression with sin(x), cos(x), tan(x) rewritten in
terms of tan(x/2) and sinh(x), cosh(x), tanh(x) rewritten in
terms of exp(x).
