404 Functions and commands

orthocenter Shows the orthocenter of the triangle made with three points.

orthocenter((Pnt or Cplx),(Pnt or Cplx),(Pnt

or Cplx))

Example:

orthocenter(0,4i,4) returns (0,0)

orthogonal With a point (A) and a line (BC) as arguments, draws the

orthogonal plane of the line that passes through the point.

With a point (A) and a plane (BCD) as arguments, draws the

orthogonal line of the plane that passes through the point.

orthogonal(Pnt(A),(Line(BC) or Plane(BCD))

Example:

orthogonal(A,line(B,C)) draws the orthogonal

plane of line BC through A and

orthogonal(A,plane(B,C,D)) draws the orthogonal

line of plane(B,C,D) through A.

pa2b2 Takes a prime integer n congruent to 1 modulo 4 and returns

[a,b] such that a^2+b^2=n.

pa2b2(Intg(n))

Example:

pa2b2(17) gives [4,1]

pade Returns the Pade approximation i.e. a rational fraction P/Q

such that P/Q=Xpr mod x^(n+1) or mod N with degree(P)<p.

pade(Expr(Xpr), Var(x), (Intg(n) || Poly(N)),

Intg(p))

Example:

pade(exp(x),x,10,6) gives (-x^5-30*x^4-420*x^3-

3360*x^2-15120*x-30240)/(x^5-30*x^4+420*x^3-

3360*x^2+15120*x-30240)

parabola With two points (F, A) as arguments, draws a parabola of

focus F and top A. With three points (F, A and P) as

arguments, draws a parabola with focus F and top A in the

plane ABP. With a complex (A) and a real (c) as arguments,

draws a parabola of equation y=yA+c*(x–xA)^2. With one

second degree polynomial (P(x,y)) as argument, draws the

parabola when the polynomial is set to equal 0.

parabola(Pnt(F)||Pnt(xA+i*yA),Pnt(A)||Real(c)

,[Pnt(P)])
