The aim of the module is to introduce the students to the fundamental ideas of Real Analysis: limits of sequences, infinite series, limits of real functions, continuity, differentiability and the Riemann integral. The module should encourage students to think clearly and critically and to begin to be able to prove simple statements on their own.
At the end of the module students should:
- Understand the Axiom of Completeness.
Understand the concept of a limit.
Be able to determine whether some simple sequences and series diverge or converge.
Understand the differences between convergence and absolute convergence.
Be able to prove statements on their own using "epsilon" arguments.
- Understand, and be able to test, the continuity of functions of one real variable.
- Understand the derivative as a limit.
- Understand some of the properties and consequences of continuity and differentiability.
- Understand the Riemann integral and some of its properties.
- Discussion of the Real Numbers with least upper bound, greatest lower bound and completeness.
- Definition and properties of the limit of a sequence, including the algebra of limits.
- Bounded Monotone Convergence.
- The exponential function.
- Subsequences and the Bolzano-Weierstrass Theorem.
- Cauchy Sequences.
- Series, including absolute and conditional convergence.
- Tests for convergence: Comparison Test, Ratio Test, Condensation Test, (including a proof that the harmonic series diverges), Alternating Series Test.
- Power Series and the Radius of Convergence.
- Limit of a function at a point, both, epsilon-delta and sequential versions, and the algebra of limits.
- Continuity of a function.
- A continuous function on a closed bounded interval attains its extrema.
- Intermediate value theorem.
- Derivative as a limit, differentiability and the algebra of derivatives.
- Rolle's theorem, the Mean Value Theorem, Taylor's Theorem.
- The Riemann integral and the Fundamental Theorem of Calculus.
