The notion of limit and convergence are two key ideas on which rest most of modern Analysis. This module aims to present these notions building on the experience gained by students in first year Calculus module. The context of our study is: limits and convergences of sequences and series of real numbers, and sequences and series of functions. These classical results will be applied to derive properties of continues and differentiable functions. The module will introduce tools that are of importance in applications, for instance, power series expansions of functions, etc.
Aims and Objectives
Having successfully completed this module you will be able to:
- Determine whether a sequence of real numbers converges, either by evaluating the limit directly or by showing the sequence is bounded and monotone
- Prove using the definition that a given sequence converges to a given limit
- Determine whether a series of positive terms converges, either by explicitly summing the series or by using a test, such as the comparison test, the ratio test, the root test, or the integral test
- Define an improper integral
- Determine whether a given improper integral converges
- Determine a radius and interval of convergence for a given power series
- Understand when one can differentiate and integrate a power series
- Find the Taylor series of a given function
