Wolfram Demonstrations Project: 3D Graph of a General Quadratic Form - 1 views
-
The graph of the equation ax^2 + by^2 + cz^2 + dxy + exz + fyz +gx + hj + i z + j=0 is shown for your settings of the parameters.
-
Set d=e=f=0 to keep things regular. Can you find a value of the settings where one parameter makes the surface shift from hyperboloids of two sheets to one?
