Module aims
The aim of the module is to describe how techniques from advanced calculus and linear algebra may be used to give meaning to the concept of "shape" for curves and surfaces in space.
Module learning outcomes
At the end of the module you should be able to:
- Understand the curvature and torsion of a space curve, how to compute them, and how they suffice to determine the shape of the curve.
- Understand the definition of a smooth surface, and the means by which many examples may be constructed.
- Understand the various different types of curvature associated to a surface, and how to compute them.
- Understand the first and second fundamental forms of a surface, how to compute them, and how they suffice to determine the local shape of the surface.
- Appreciate the distinction between intrinsic and extrinsic aspects of surface geometry.
Module content
