Lab 5: Local Theory of Surfaces
Introduction
In this lab we introduce the local theory of surfaces in three-dimensional
space. This subject is the natural extension of the study of the local theory
of plane curves and space curves. As we did for plane curves and space curves,
we will introduce coordinate representation and vector notation for surfaces.
Next, we will define a particular family of plane curves on a surface, the
parametric curves, and use these to define the metric coefficients, which
help us to characterize classes of surfaces. The metric coefficients provide
us with a tool for computing not only lengths of curves but also areas
of regions and angles between curves on a surface.
