(If the variable X has the value 90)
Uses the EZ GCD algorithm to return the greatest common
divisor of two polynomials with at least two .
ezgcd(Poly,Poly)
Returns a list consisting of the numerator and denominator of
an irreducible form of a rational fraction.
f2nd(RatFrac)
Returns the list of the faces of a polygon or polyhedron. Each
face is a matrix of n rows and three columns (where n is the
number of vertices of the polygon or polyhedron).
faces(Polygon or Polyedr)
Returns the factorial of an integer or the solution to the gamma
function for a non-integer.
factorial(Intg(n)||Real(a))
Returns the value of the abscissa at the maximum value of an
expression. Without a second argument, it is assumed that it
the abscissa is x. With a variable as second argument, it is
taken as the abscissa.
fMax(Expr,[Var])
Returns the value of the abscissa at the minimum value of an
expression. Without a second argument, it is assumed that it
the abscissa is x. With a variable as second argument, it is
taken as the abscissa.
fMin(Expr,[Var])
Used in programming in loops for which the number of
iterations is known.
Returns a real number as a string with the indicated format
(f=float, s=scientific, e=engineering).
format(Real,Str("f4"||"s5"||"e6"))
For a given integer n (representing a fraction) and an integer
p (the modulus), returns the fraction a/b such that n=a/b(mod
p).
fracmod(Intg(n),Intg(p))
