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 = -1.2..5.05, y = -1..2,
        style = patchcontour,        
        orientation = [114, 73]);

[Maple Plot]

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,
        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,
               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,
                   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,
                          numpoints = 500):
  Bildfolge:= [op (Bildfolge), Bild]:
od:
display (Bildfolge, insequence = true);
