Please be patient while your browser is loading Surface Plotter classes.
Hints for using Surface Plotter:
plots an explicitly
defined function z = f(x,y).
All multiplications must use *.
Calculate <- draws the function.
Options | Show xy ticks and | Show z ticks puts axes.
Options | gray scale gives a nice picture. You can drag the function around using your left mouse button.
Options | Contour plot gives level curves.
See Help menu in the applet to look up all functions
Here are some examples:
z=x^2 + y^2
z = exp(x^2 - y^2)
z = if (x>0,x+y,0)
z = if(x <= 0, if(x = 0, 0, -1), 1) (sign function)
