By means of translations and rotations (changes of coordinates), this equation can be simplified into standard forms. Quadratic surfaces are the 3D analogs of conic sections (ellipses, parabolas, hyperbolas) in 2D.

1. Introduction A quadratic surface (or quadric) is the graph in three-dimensional space of a second-degree equation in three variables. The general equation is: By means of translations and rotations (changes of
