Credits: 6
Level: Honours (FHEQ level 6)
Period: Semester 1
Assessment: EX 100%
Supplementary Assessment: MA30039 Mandatory Extra Work (where allowed by programme regulations)
Requisites: Before taking this unit you must (take MA20007 and take MA20008 and take MA20011 and take MA20012) or (take MA20216 and take MA20218 and take MA20219)
Description: Aims:
This course will use vector calculus to develop the local differential geometry of curves and surfaces in Euclidean 3-space. In this way, an introduction is given to an area of mathematics which has been the subject of active research for over 200 years.

Learning Outcomes:
At the end of the course, the students will be able to apply the methods of calculus with confidence to geometrical problems. They will be able to compute the curvatures of curves and surfaces and understand the geometric significance of these quantities.

Content:
Topics will be chosen from the following:
* Parametrizations, tangent spaces, tangent maps.
* Euclidean motions.
* Curves: length of curves; arc-length; normal fields; curvatures and torsion; normal connection; parallel transport; Frenet curves; Frenet formulae; fundamental theorem; isoperimetric inequality; four-vertex theorem.
* Surfaces: induced metric; conformal parametrization; Gauss map; shape operator; mean, Gauss and principal curvatures; curvature line parametrization; covariant derivative/Levi-Civita connection; Koszul's formulae; curvature tensor; Gauss-Weingarten equations; Gauss-Codazzi equations; Bonnet's theorem.
* Curves on surfaces: geodesics; geodesic curvature; geodesic polar coordinates; geodesics as local length minimizers; Minding's theorem; Clairaut's theorem; normal curvature; Euler's theorem; Meusnier's theorem; asymptotic lines; curvature lines; Rodrigues' equation; Joachimsthal's theorem; integration on surfaces; Gauss-Bonnet theorem.
* Special surfaces: minimal surfaces; surfaces of constant mean or Gauss curvature; ruled surfaces; developable surfaces.
