This module introduces a number of powerful ideas found in all area of mathematics and its applications that are broadly geometric in flavour. Complex numbers, which turn out to underpin a profound unification of many ideas in mathematics, are introduced. Vectors, which have both magnitude and direction, provide a natural way to describe lines and planes and are the appropriate language with which to model physical systems in mechanics. Matrices provide both a convenient way to deal with large systems of linear equations and to transform vectors and coordinate systems. This in turn leads to the theory of linear algebra and vector spaces. The abstraction of the notion of a vector space is another powerful unifying theory that is found across mathematics, with applications in abstract group theory, video games and signal processing. Coordinate systems for the Euclidean plane are discussed and the standard theory of conic sections is developed. The module also introduces the fundamental proof technique of Mathematical Induction.
