Description:  Aims: The aim of this unit is to introduce mathematical concepts and techniques required by science students, and to show how these may be used for different applications. It also aims to continue the development of students' problemsolving skills and their understanding of mathematical results. Learning Outcomes: After taking this unit the student should be able to: * find the eigenvalues and eigenvectors of matrices; * calculate the normal modes of coupled vibrational systems; * calculate and interpret derivatives of vector functions of 1 variable; * parameterise curves; * define and transform between Cartesian, plane polar, cylindrical polar and spherical polar coordinates; * visualise points, lines, planes and volumes in these coordinates; * define scalar, vector and conservative fields; * evaluate and interpret grad, ^{2} and directional derivatives of scalar fields in the above coordinate systems; * evaluate and interpret div and curl of vector fields in the above coordinate systems; * evaluate and interpret line, surface and volume integrals in the above coordinate systems; * identify conservative fields and find their potential functions; * use and interpret vector integral theorems. Skills: Numeracy T/F A, Problem Solving T/F A. Content: Eigenvalues and eigenvectors (6 hours): Revision of matrix algebra.
