perimeteratraw(Polygon, Pnt||Cplx(z0))
plane(A,B,C) or plane(A,line(B,C)) (resp
plane(a*x+b*y+c*z+d=0)) draws the plane ABC (resp of
equation a*x+b*y+c*z+d=0) in the 3-D space.
plane(Pnt or Eq, [Pnt or Line],[Pnt])
Returns the line of the conjugated points of A with respect to
the circle.
polar(Crcle,Pnt or Cplxe(A))
Returns the list of the norm and of the argument of the affix of
a point (for 2-D) or of a complex number or of the the list of
rectangular coordinates.
polar_coordinates(Pnt or Cplx or LstRectCoord)
Returns the point having the line as polar with respect to the
circle.
pole(Crcle,Line)
Draws a convex polyhedron with vertices among the
arguments.
polyhedron(SeqPnt(A,B,C...))
Returns the real number d^2-R^2 (d=distance between point
and center, R=radius) .
powerpc(Circle,Pnt or Cplx)
Draws a prism with plane base ABCD...and with edges
parallel to AA1 (the faces are parallelograms).
