# Mathematics 1A20

## Unit aims

To consolidate, develop and extend the skills in single variable calculus introduced at A level.

## Unit description

This unit is designed for students with a good grasp of A level mathematics who want a 20 credit-point unit on mathematical techniques.

The unit begins with some basic ideas revising and extending school-level calculus, and then goes on to a thorough treatment of the calculus from the point of view of scientific applications. The subject is developed as far as differential equations and Fourier series. The mathematics is treated with enough logical precision to enable correct calculations and correct deductions to be made.

## Relation to other units

There are no follow-on units for this course.

## Learning objectives

After taking this unit, students should have a thorough grasp of one-variable calculus and complex numbers, including simple differential equations and Fourier Series.

## Transferable skills

Mathematical techniques for application in the physical sciences.

## Syllabus

The numbers of lectures (shown in brackets) are a rough guide only.

**Unit code:** MATH11004

**Level of study:** C/4 (Open)

**Credit points:** 20

**Teaching block (weeks):** 1 (1-12)

**Lecturer:** Dr Yves Tourigny

## Pre-requisites

A-level Mathematics, or equivalent.

## Co-requisites

None

## Methods of teaching

The unit is based on lectures and tutorials on how to apply the techniques of the calculus in solving problems.

The lecturer will distribute problem sheets based on the work done in lectures, and will set specific problems which you will be required to hand in to tutors for marking. Once the course is under way, students will attend weekly tutorials in which homework questions and additional problems will be covered.

**Tutorials**

Weekly tutorials will be held after the first or second week. You will be given the time of your tutorial. Experience shows that progress in mathematics depends crucially on regular work at examples. For this reason you are REQUIRED to attend the tutorials and to hand in the set work.

## Methods of Assessment

The pass mark for this unit is 40.

The final mark is calculated as follows:

- 100% from a 2 hour 30 minute exam in January*

**There are two parts to the exam; Part A consists of 8 shorter questions, Part B consists of 4 longer questions. ALL questions will be used for assessment. Part A contributes 40% and Part B contributes 60% of the overall mark for the paper.*

NOTE: Calculators of an approved type (non-programmable, no text facility) are allowed.

Candidates may bring into the examination room one A4 double-sided sheet of notes.
