| In [[algebraic geometry]], the '''Cayley surface''',named after [[Arthur Cayley]], is a [[cubic surface]] in 3-dimensional [[projective space]] with four conical points. It can be given by the equation
| |
| | |
| :<math> wxy+ xyz+ yzw+zwx =0\ </math>
| |
| | |
| when the four singular points are those with three vanishing coordinates.
| |
| Changing variables gives several other simple equations defining the Cayley surface.

Andrew best psychic (http://conniecolin.com) Berryhill is what his wife enjoys to call him and he completely digs that title. I've usually cherished residing in Kentucky but now I'm considering other choices. To climb is some thing I truly enjoy performing. My day job is an invoicing officer but I've currently utilized for an additional 1.
