DIFFERENTIAL GEOMETRY OF CURVES AND SURFACES 3. …

Examples of surfaces. 1. Let S be the horizontal coordinate plane, which consists of all points (x,y,0) with x,y in R. We claim that S is a surface, in the sense of Definition 3.1.1. To see that, we take U to be the whole R2 and ϕ : R2 → S given by ϕ(u,v) = (u,v,0), for all (u,v) in R2. It s obvious that any point P = (x,y,0) of S is in ...
