### MAS1603 : Multivariable Calculus and Differential Equations

• Offered for Year: 2019/20
• Module Leader(s): Dr Paul Bushby
• Owning School: Mathematics, Statistics and Physics
• Teaching Location: Newcastle City Campus
##### Semesters
 Semester 2 Credit Value: 15 ECTS Credits: 8.0

#### Aims

To develop an understanding of ordinary differential equations and a familiarity with relevant solution methods. To introduce the calculus of functions of several variables.

Module summary

This module, which continues and extends the work of MAS1601, develops many of the ideas that are needed when constructing mathematical models of phenomena in the real world. Many such models are formulated in terms of ordinary differential equations, and this module introduces the methods that are needed to solve problems of this type. The world where we live is multi-dimensional - three-dimensional if we consider spatial dimensions alone, or four-dimensional if we treat time as another variable. It is therefore essential to develop tools to describe and model objects and processes that occur in multi-dimensional spaces. In order to do this we require multidimensional calculus. This module introduces the partial derivative, and the multiple integral, as well as power series in two or more variables.

#### Outline Of Syllabus

Introduction to ordinary differential equations (ODEs): terminology and examples.

First-order ODEs: separable equations, homogeneous equations, integrating factor. Existence and uniqueness of the initial value problem for first-order ODEs, singular points and integral curves of first-order ODEs.

Second-order ODEs: homogeneous equations with constant coefficients, particular integrals for inhomogeneous equations, method of variation of parameters.

Introduction to functions of several variables: partial differentiation, gradient, chain rule and Jacobian matrices.

Taylor series in two (or more) variables, classification of stationary points.

Multiple Integrals: double and triple integrals, change of variables (including polar coordinates).

##### Teaching Rationale And Relationship

Lectures are used for the delivery of theory and explanation of methods, illustrated with examples, and for giving general feedback on marked work. Problem Classes are used to help develop the studentsâ€™ abilities at applying the theory to solving problems. Tutorials are used to identify and resolve specific queries raised by students and to allow students to receive individual feedback on marked work. In addition, office hours (two per week) will provide an opportunity for more direct contact between individual students and the lecturer: a typical student might spend a total of one or two hours over the course of the module, either individually or as part of a group.

#### Assessment Methods

##### Assessment Rationale And Relationship

A substantial formal unseen examination is appropriate for the assessment of the material in this module. The coursework assignments will consist of one written assignment (approximately 3%), one assignment laboratory (approximately 3%) and two computer based assessments (each approximately 2%). The coursework assignments and the (in class, therefore 40 minute) coursework test allow the students to develop their problem solving techniques, to practise the methods learnt in the module, to assess their progress and to receive feedback; these assessments have a secondary formative purpose, as well as their primary summative purpose.
