# Module Overview

### Linear Algebra and Calculus

This module will impart the essential foundational elements of linear algebra in a matrix representation. The learner will carry out the basic calculations of matrix algebra, while interpreting these concepts geometrically. They will then expand their knowledge of calculus to include more methods of integration and to the solution of number of classes of ordinary differential equations. Finally they will apply their knowledge of calculus to power series and Fourier series representations of functions.

The calculus element of this module is best thought by introducing the methods of solution for ODEs, Series, Transforms and so on in lectures, explaining how and why they work and then practising as many examples as feasibly possible in the time allowed. The Matrices content is also best taught with examples provided via worksheets.
