Functions and commands

407

plane

With three points as arguments, draws the plane made by the

three points. With a point and a line as arguments, draws the

plane made by the point and the line. With an equation as

argument, draws the plane corresponding to the equation in

3D space.

plane(Pnt or Eq, [Pnt or Line],[Pnt])

plotinequation

Draws the points of the plane whose coordinates satisfy the

inequations of two

plotinequation(Expr,[x=xrange,y=yrange],[xste
p],[ystep])

plotparam

With a complex (a(t)+i*b(t)) and a list of values for the

variable (t) as arguments, draws the parametric representation

of the curve defined by x=a(t) and y=g(t) over the interval

specified in the second argument. With a list of expressions of

two variables (a(u,v),b(u,v),c(u,v)) and a list of values for the

variables (u=u0...u1,v=v0...v1) as arguments, draws the

surface defined by x=a(u,v), y=b(u,v), and z=c(u,v) over the

intervals specified by in the second argument.

plotparam(Cplx||Lst,Var||Lst(Var))

plotpolar

For an expression f(x), draws the polar curve r=f(x) for x over

the interval VarMin to VarMax.

plotpolar(Expr,Var,VarMin,VarMax)

plotseq

Displays the pth terms of the sequence u(0)=a,u(n)=f(u(n–1)).

plotseq(Expr(f(Var)),Var=[a,xm,xM],Intg(p))

point

With a complex as argument, plots it. With the coordinates of

a point in three dimensions as argument, plots it.

point(Cplx||Vect)

polar

Returns the line of the conjugated points of A with respect to

a circle.

polar(Crcle,Pnt or Cplx(A))

polar_coordinates

Returns the list of the norm and of the argument of the affix of

a point, complex number or list of rectangular coordinates.

polar_coordinates(Pnt or Cplx or LstRectCoord)

Example:

polar_coordinates(point(1+2*i))

gives

[sqrt(5),atan(2)]
