Can anyone suggest any basic *undergraduate* differential geometry texts on the same level as Manfredo do Carmo's *Differential Geometry of Curves and Surfaces* other than that particular one? (I know a similar question was [asked earlier][1], but most of the responses were geared towards Riemannian geometry, or some other text which defined the concept of "smooth manifold" very early on. I am looking for something even more basic than that.) [1]: https://mathoverflow.net/questions/395/reading-list-for-basic-differential-geometry
