**Synergies: **Analysis is one of the two most fundamental parts of pure mathematics with the other being algebra. This module forms the foundation on which many other modules will be built. Amongst the first year modules, the ones most closely related are: MA133 Differential Equations and MA134 Geometry and Motion. Analysis also has close connections to applied mathematics, probability theory and physics.

**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

**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 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, concerning sequences and series in term one, continuity and differentiability in term two and integration in term one of your second year.

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 $ \pi $ or *$e$* or $\sqrt{2}$ ? How can you add up infinitely many numbers, or infinitely many functions? Can all functions be approximated by polynomials?

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.
