Graphing websites
Does anyone know of a good implicit graphing website that would allow me to graph the following functions?

1) y^2 + z^2 = 4
2) x^2 + 9y^2 + 4z^2 = 36
3) 4x^2 + 9y^2 = 36
4) y^2 + z^2 = 4x^2

Here's one I found, but I can't get it to graph.

Maybe you'll have some luck.

Implicit Function Graphing Tool

I doubt if it'll graph 3-D, though.

You can use Maple or Mathematica.
For example, the following Maple code will graph the first equation:

implicitplot3d(y^2+z^2=4,x=-2..2,y=-2..2,z=-2..2);

Are you using Maple 10?

No. I am using Maple 8. The basic functions are similar.

I like maths helper its basic and easy to use for graphing.
