# MA139 Analysis 2

**Lecturer:** Keith Ball

**Term(s):** Term 2

**Status for Mathematics students:** Core

**CAUTION: **This entry refers to arrangements for students based in the Mathematics Department (those who entered through the Mathematics Department and have a Personal Tutor there). All other students should be registered on MA152 Mathematical Analysis 2.

**Commitment:** 30 lectures, written assignments

**Assessment: **Weekly assignments (15%), June exam (85%)

**Formal registration prerequisites: **None

**Assumed knowledge: **MA141 Analysis I

**Useful background:**

**Synergies: **Analysis is one of the two most fundamental parts of pure mathematics, the other being Algebra. This module and the first term module MA141 Analysis I form the foundation on which many other modules will be built. Amongst the first year modules, the one most closely related is MA141 Analysis I but analysis also has close connections to applied mathematics, probability theory and physics. The most natural synergies are therefore:

- MA141 Analysis 1
- MA144 Methods of Mathematical Modelling 2
- MA146 Methods of Mathematical Modelling 1

**Leads to: **The following modules have this module listed as **assumed knowledge** or **useful background:**

- MA222 Metric Spaces
- MA260 Norms, Metrics and Topologies
- MA254 Theory of ODEs
- MA259 Multivariable Calculus
- MA4J1 Continuum Mechanics

**Aims**:

**Content**:

At the beginning of the nineteenth century, the familiar tools of calculus, differentiation and integration, began to run into problems. Mathematicians were unsure of how to apply these tools to sums of infinitely many functions. The origins of Analysis lie in their attempt to formalize the ideas of calculus purely in the language of arithmetic and to resolve these problems.

You will study ideas of the mathematicians Cauchy, Dirichlet, Weierstrass, Bolzano, D'Alembert, Riemann and others. Following on from the material concerning sequences, series and continuity in term one, you will study differentiation and integration in term two.

By the end of the year you will be able to answer many interesting questions: What do we mean by `infinity'? How can you accurately compute the value of π or e or √2 ? How can you add up infinitely many numbers, or integrate a function?

There will be considerable emphasis throughout the module on the need to argue with much greater precision and care than you had to at school. With the support of your fellow students, lecturers and other helpers, you will be encouraged to move on from the situation where the teacher shows you how to solve each kind of problem, to the point where you can develop your own methods for solving problems. You will also be expected to question the concepts underlying your solutions, and understand why a particular method is meaningful and another not so. In other words, your mathematical focus should shift from problem solving methods to concepts and clarity of thought.
