x(u,v) = (1+\frac{v}{2}\cos \frac{u}{2})\cos u
x(u,v)=(1+2vcos2u)cosu
y(u,v) = (1+\frac{v}{2}\cos \frac{u}{2})\sin u
y(u,v)=(1+2vcos2u)sinu
z(u,v) = \frac{v}{2}\sin \frac{u}{2}
z(u,v)=2vsin2u
a one-sided nonorientable surface obtained by cutting a closed band into a single strip, giving one of the two ends thus produced a half twist, and then reattaching the two ends
