376 Functions and commands
append Appends an element to a list, sequence or set.
append((Lst||Seq||Set,Elem)
Example:
append([1,2,3],4)
gives
[1,2,3,4]
apply Returns the result of applying a function to the elements in a
list.
apply(Fnc,Lst)
Example:
apply(x->x^3,[1,2,3])
gives
[1,8,27]
approx With one argument, returns the numerical evaluation of it.
With a second argument, returns the numerical evaluation of
the first argument with the number of significant figures taken
from the second argument.
approx(Expr,[Int])
areaat Displays the algebraic area at point z0 of a circle or a
polygon. A legend is provided.
areaat(Polygon,Pnt||Cplx(z0))
areaatraw Displays the algebraic area at point z0 of a circle or a
polygon.
areaatraw(Polygone,Pnt||Cplx(z0))
ASIN Arc sine: sine –1 x.
ASIN(value)
assume Used in programming to state an assumption about a
variable.
assume(Expr)
ATAN Arc tan: tan –1 x.
ATAN(value)
barycenter Draws the barycenter of the system consisting of point 1 with
weight coefficient 1, point 2 with weight coefficient 2, point 3
with weight coefficient 3, etc.
barycenter([Pnt1,Coeff1],[Pnt2,Coeff2],[Pnt3,
Coeff3])
Example:
barycenter([–3,1],[3,1],[4,2])
gives
point(2,0)
