polar_point Returns the point with polar coordinates r and t.
polar_point(Real(r),Real(t))
pole Returns the point for which the line is polar with respect to the
circle.

POLYCOEF Returns the coefficients of a polynomial with roots given in the
vector argument.
polyCoef(Vect)
Example:
POLYCOEF({-1, 1})
returns
{1, 0, -1}
POLYEVAL Evaluates a polynomial given by its coefficients at x0.
polyEval(Vect,Real(x0))
Example:
POLYEVAL({1,0,-1},3)
returns
8
polygon Draws the polygon whose vertices are elements in a list.
polygon(LstPnt||LstCplx)
Example:
polygon(GA,GB,GD) draws ΔABD
polygonplot Draws the polygons made by joining the points (xk,yk), where
xk=element row k column 0 and yk=element row k column j
(for j fixed and for k=0...nrows).
polygonplot(Mtrx)
polygonscatterplot Draws the points (xk,yk) and the polygons made by joining
the points (xk,yk), where xk=element row k column 0 and
yk=element row k column j (for j fixed and for k=0...nrows).
polygonscatterplot(Mtrx)
polyhedron Draws a convex polyhedron whose vertices are the points in
the sequence.
