# Roman Surface

The Roman surface is a *quartic nonorientable surface*. It – along with *Boy’s Surface* and the *Cross-cap* – are the three surfaces that can be crafted by pasting a *Möbius Strip* to the edge of a disc.

The following is one of its parametrizations (Weisstein (2016)):

\[% \begin{split} x(u,v) & = \frac{1}{2} a \sin{2u} \sin2 v\\ y(u,v) & = \frac{1}{2} a \sin u \cos{2v}\\ z(u,v) & = \frac{1}{2} a \cos u \sin{2v}\\ \end{split}% \]

where \(u \in [ 0, 2\pi )\) and \(v \in [-\pi/2,pi/2]\).
