Functions and commands
SIN(value)
Returns an expression with the complex exponentials rewritten
in terms of sin and cos.
sincos(Expr)
With two curves or two surfaces as arguments, returns one of
the intersections of the two curves or surfaces. With to curves
or surfaces and a point or list of points as arguments, returns
an intersection of the curves or surfaces that is nearest to the
point or not in the list of points.
single_inter(Curve,Curve,[Pnt(A)||LstPnt(L)])
Displays the value at point z0 of the slope of the line or
segment d. A legend is provided.
slopeat(Line,Pnt||Cplx(z0))
Displays the value at point z0 of the slope of the line or
segment d.
slopeatraw(Line, Pnt||Cplx(z0))
With two points as arguments, draws the sphere of diameter
made by the line from one point to another. With a point and
a real as arguments, draws the sphere with center at the point
and radius given by the real.
sphere((Pnt or Vect),(Pnt or Real))
Returns the natural spline through the points given by two lists.
The polynomials in the spline are in variable x and of degree
d.
spline(Lst(lx),Lst(ly),Var(x),Intg(d))
Returns the square root of an expression.
sqrt(Expr)
Draws the square of side AB in the plane ABP.
square((Pnt(A) or Cplx),(Pnt(B) or
Cplx),[Pnt(P),Var(C),Var(D)])
Returns the standard deviance of the elements in a list with the
second argument as pound
deviances of the columns of a matrix.
