The basket shaped surface shown in this figure is a finite portion of an elliptic paraboloid. The elliptic paraboloid is a non-ruled quadric surface, i.e. a surface of degree 2 that does not contain an infinite family of straight lines. In fact, there are no straight lines on this surface. The equation of this elliptic paraboloid is z = x² + y²/2.25, or equivalently 9z = 9x² + 4y². This instance is not a surface of revolution. |
