General description
The purpose of this module is to present some of the basic concepts of algebra at a level suitable for applications in other areas. The syllabus includes the solution of polynomial equations, complex numbers, trigonometric functions, graphs. The binomial theorem and solution of linear equations by row reductions of matrices.

Aims
To introduce students to algebraic ideas, at a level suitable for application in subjects other than Mathematics.

Learning outcomes
On completion of this module, a student should be able to:

• manipulate trigonometric functions and use trigonometric identities;
• solve certain polynomial equations;
• manipulate matrices;
• solve a system of linear equations using row reduction of matrices;
• find the eigenvalues and corresponding eigenvectors of a matrix;
• form inverse functions;
• use the binomial theorem and the binomial series.
