NoneAims
To give an introduction to the basic ideas of geometry and topology.
Overview
This course unit introduces the basic ideas of Euclidean and affine geometry, quadric curves and surfaces in Euclidean space, and differential forms, and the first ideas of projective geometry. These notions permeate all modern mathematics and its applications.
Learning outcomes
On successful completion of this module students will be able to:
- Calculate orientation of bases in vector space
- State the Euler Theorem about rotations in E^{3}. Calculate the axis and an angle of rotation in E^{3} for an orthogonal operator preserving orientation.
- Define a differential 1-form in E^{n}. Calculate the values of 1-forms on vectors. Calculate differential of functions and the directional derivative of a function along a vector. Calculate integrals of differential 1-forms over curves.
- Establish relations between analytic and geometric definitions of conic sections. In particular find foci of an ellpse, and find focus and directrix of a parabola given by analytic expressions.
- Find cross-ratio of four collinear points on projective plane. Find projective transformations of conic sections.

Feedback methods
Feedback tutorials will provide an opportunity for students' work to be discussed and provide feedback on their understanding. Coursework or in-class tests (where applicable) also provide an opportunity for students to receive feedback. Students can also get feedback on their understanding directly from the lecturer, for example during the lecturer's office hour.
