# Algebra and Analysis

## Overview

• Credit value: 30 credits at Level 6
• Convenor: Steven Noble
• Assessment: short written assignments (20%) and a two-hour examination (80%)

## Module description

In this module you will learn key concepts from abstract algebra and analysis. The module builds on the Level 5 modules Algebra 2 and Calculus 2. One half covers material on algebraic structures such as groups, rings, fields and vector spaces, giving you a thorough grounding in these topics. The other half provides the theoretical background to calculus, formally defining the idea of a limit, continuity and differentiability of a function and the Riemann integral.

The learning materials for this module comprise a mixture of short instructional videos, online quizzes to test your understanding, face-to-face examples classes, full course notes, and exercises to try at home.
