# VECTOR CALCULUS - 2023/4

Module code: MAT1005

## Module Overview

The main focus of this module is on multivariable calculus in 2 and 3 dimensions, and vector calculus. This extends knowledge developed in A-levels and in the Year 1 module Calculus on the differentiation and integration of functions of a single variable, and provides the necessary ground work for Years 2 and 3 modules, such as Curves and Surfaces, Linear PDEs, Fluid Mechanics and Functions of a Complex Variable.

## Assessment Strategy

The __assessment strategy__ is designed to provide students with the opportunity to demonstrate understanding through the solution of unseen and similar to seen problems in the test and exam, which relate to:

Geometric problems with vectors in 2 and 3 dimensions.

Problems in multivariable differential calculus in 2 and 3 dimensions.

Double and triple integrals.

Scalar and vector fields, and differential operators.

Line and surface integrals.

Green’s theorem, Stoke’s theorem and the Divergence Theorem.

Thus, the

__summative assessment__for this module consists of:

One two hour examination at the end of the semester – worth 75% of the module mark.

One in-semester test – worth 25% module mark.

__Formative assessment and feedback__

Students receive written feedback via a number of marked coursework assignments over an 11 week period. Additional verbal feedback will be provided by the lecturer or a tutor at seminars.

## Module aims

- Revisit the geometry of vectors, and curves and surfaces in 2 and 3 dimensions.
- Introduce students to multivariable calculus in 2 and 3 dimensions, including:

1) Differential calculus of functions of 2 and 3 variables;

2) Double and triple integrals. - Introduce students to vector calculus in 3 dimensions, including:

1) Differential operators, such as div, grad and curl;

2) Line and surface integrals;

3) Green’s theorem, Stoke’s theorem and the Divergence Theorem. - Enable students to solve problems related to each of these topics.

## Methods of Teaching / Learning

The __learning and teaching__ strategy is designed to:

Extend students’ knowledge of vectors, and geometry in 2 and 3 dimensions.

Provide students with a detailed introduction to multivariable calculus in 2 and 3 dimensions, and vector calculus in 3 dimensions.

Experience (through demonstration) of the methods used to interpret, understand and solve problems in multivariable calculus and vector calculus.

The

__learning and teaching__methods include:

4 x 1 hour lectures per week x 11 weeks – material and examples supplementing the module notes will be presented on blackboards/whiteboards, with Q & A opportunities for students.

1 x 1 hour seminar in alternate weeks x 5 weeks – a guided discussion of solutions to problem sheets, provided to and worked on by students in advance.

Indicated Lecture Hours (which may also include seminars, tutorials, workshops and other contact time) are approximate and may include in-class tests where one or more of these are an assessment on the module. In-class tests are scheduled/organised separately to taught content and will be published on to student personal timetables, where they apply to taken modules, as soon as they are finalised by central administration. This will usually be after the initial publication of the teaching timetable for the relevant semester.
