Funktionen von zwei Veränderlichen

Beispiel 1:

> z1:= x*(x^2 + y^2)/(x-y);

z1 := x*(x^2+y^2)/(x-y)

> plot3d(z1,
    x = 2..5, y = 1.7..1.9,
    style = polygonoutline,        
    orientation = [129, 58]);

Beispiel 2:

> z2:= sin(x) + sin(y);

z2 := sin(x)+sin(y)

> plot3d(z2,
    x = -1.5*Pi..1.5*Pi,
    y = -1.5*Pi..1.5*Pi,
    font = [COURIER, 12],
    axes = boxed);

Beispiel 3:

> with(plots):
     Warning, the name changecoords has been redefined

> f(x,y):= x^3 - y^3;

f(x,y) := x^3-y^3

> implicitplot(f(x,y)= x + y,
    x = -2..2,
    y = -3..3,
    numpoints = 2000,
    font = [COURIER, 12],
    thickness = 2);

Beispiel 4:

> gl:= sqrt(a*x^2 + b*y^2) = exp(k*(x + y)): gl;

> gl1:= subs({a = 2, b = 1, k = 1/3}, gl):
  implicitplot(gl1, x = -4..8, y = -10..10,
    thickness = 2,
    font = [COURIER, 12],
    color = blue);

> Bildfolge:= [ ]:
  for k from 0.23 to 0.35 by 0.005 do
    Bild:= implicitplot(subs({a = 2, b = 1}, gl),
      x = -4..4,
      y = -1..10,
      thickness = 2,
      color = red,
      axesfont = [COURIER, 12],
      labels = ["", ""],
      numpoints = 500):
    Bildfolge:= [op(Bildfolge), Bild]:
  od:
  display(Bildfolge, insequence = true);
