MA20007 Analysis: Real numbers, real sequences & series

Credits: 6
Level: Intermediate
Semester: 1
Assessment: EX 100%
Before taking this unit you must take MA10004 and take MA10005 and take MA10006

Aims & Learning Objectives:
Aims: To reinforce and extend the ideas and methodology (begun in the first year unit MA10004) of the analysis of the elementary theory of sequences and series of real numbers and to extend these ideas to sequences of functions.
Objectives: By the end of the module, students should be able to read and understand statements expressing, with the use of quantifiers, convergence properties of sequences and series. They should also be capable of investigating particular examples to which the theorems can be applied and of understanding, and constructing for themselves, rigorous proofs within this context.
