Analysis

Analysis is the branch of mathematics that asks what limits and continuity really mean. It studies differentiable and integrable functions, and it reaches into measure theory and abstract probability. It also takes the familiar theorems of calculus and proves them carefully in more abstract settings. This is where we slow down and demand precision and rigour.

Real numbers, sequences, series, limits, continuity
Differentiation, mean value theorem, Taylor expansion, L'Hospital's rules
Riemann integration, uniform convergence, uniform continuity
Lebesgue measure and integration theory, abstract probability theory and random variables
Metric spaces: convergence, completeness, compactness, connectedness
Complex analysis: holomorphic functions, contour integration, Cauchy's theorem, the Residue Theorem, Rouche's theorem, analytic continuation, the Argument Principle, the Maximum Modulus Theorem, conformal mappings

Where analysis usually trips students up

Analysis is the module most maths majors find hardest, and the difficulty is rarely the topics themselves. It is the shift in what counts as an answer.

Writing real epsilon-delta proofs. Restating the definition is not the same as using it, and the marks go to the argument that actually pins the bound down.
Getting the quantifiers in the right order. Swapping a for-all and a there-exists quietly changes the statement, and with it the whole proof.
Pointwise versus uniform convergence. The distinction looks like a technicality until it decides whether you can swap a limit with an integral or a derivative.
Proving the obvious. Facts that felt self-evident in calculus, like a continuous function on a closed interval attaining its maximum, now have to be earned.
Treating completeness and compactness as definitions to memorise. They are tools, and the skill is reaching for the right one at the right moment.
Moving from computing to justifying. The habits that earned marks in calculus have to give way to careful, written reasoning.

Before you start: an analysis prerequisites checklist

Analysis assumes a working calculus background and, above all, a willingness to prove things. Before you begin, it is worth confirming you are at home with the following.

What to be comfortable with before week one
Be comfortable with	Why it matters for analysis
Single-variable calculus	Analysis revisits limits, derivatives and integrals, so the calculus mechanics should already be routine.
Proof technique	Induction, contradiction and contrapositive are used constantly, and fluency with them is the real prerequisite.
Sets and logic	Quantifiers, unions and intersections, and negating statements correctly are the grammar of every proof here.
Functions	Domain, range, injectivity and surjectivity all return in a more demanding form.
Sequences and limits	Even an informal feel for convergence makes the formal epsilon-delta treatment far less of a shock.
Inequalities	Estimating and bounding expressions, especially with the triangle inequality, is the daily work of analysis.

A one-semester self-study plan for independent learners

Analysis is hard to rush and very rewarding to take slowly. If you are teaching yourself, perhaps to shore up the foundations behind a quantitative degree, here is a thirteen-week route map built around texts that explain their reasoning well. Work at whatever pace suits you, and reach out if the early proofs are not yet clicking, since that is where a little guidance saves the most time.

Texts I often point self-study students to
Text	Author	Best for
Understanding Analysis	Stephen Abbott	A gentle, motivation-rich first pass that makes the ideas feel inevitable
Principles of Mathematical Analysis	Walter Rudin	The classic rigorous text, concise and demanding
Introduction to Real Analysis	Bartle & Sherbert	A balanced standard course text with plenty of worked detail
Analysis I and II	Terence Tao	A careful build from the ground up, strong on why each step is needed
Real Analysis	Gerald Folland	A reference for the measure and integration material later in the plan

A thirteen-week plan
Week	Focus	Suggested reading	Checkpoint
1	The real numbers and completeness	Abbott or Rudin, opening chapter	Use the least-upper-bound property in a proof
2	Sequences and limits	Abbott or Bartle	Prove a limit straight from the definition
3	Series and convergence	Abbott or Bartle	Apply the standard convergence tests with justification
4	Limits of functions and continuity	Abbott or Rudin	Write a clean epsilon-delta continuity proof
5	Uniform continuity and the topology of the line	Rudin or Bartle	Distinguish continuity from uniform continuity
6	Differentiation and the mean value theorem	Abbott or Bartle	State and apply the mean value theorem rigorously
7	Riemann integration	Rudin or Bartle	Prove a function is integrable from the definition
8	Sequences and series of functions	Abbott or Rudin	Tell pointwise and uniform convergence apart and use the difference
9	Metric spaces: completeness and compactness	Rudin	Work with open and closed sets and compactness as tools
10	Connectedness and continuity on metric spaces	Rudin	Carry continuity arguments into the abstract setting
11	Introduction to Lebesgue measure	Folland, opening chapters	Understand what measure adds beyond the Riemann integral
12	The Lebesgue integral	Folland	State the convergence theorems and why they matter
13	Review and first steps in complex analysis	Your own course notes	Consolidate the proofs and look ahead to holomorphic functions

Frequently Asked Questions (FAQ) - Mathematical Analysis Tuition

Which analysis topics and modules do you cover?

Real analysis from the construction of the real numbers through sequences, series, continuity, differentiation and Riemann integration, then on to metric spaces, Lebesgue measure and integration, and complex analysis. That covers the analysis modules maths majors take at NUS, NTU and the other local universities, up to honours level. Send me the module details and I will confirm what I can help with.

I understood calculus but analysis feels like a different subject. Is that normal?

Completely normal, and it is the single most common thing I hear. Analysis asks you to prove what calculus let you assume, so the early weeks feel like learning a new language. Most of my work here is making that language familiar, one careful argument at a time, until the proofs start to feel natural.

How do I get better at writing epsilon-delta and other proofs?

By writing them, with feedback. We start from the definition, work out the bound on rough paper, and only then set the argument down in the order a marker expects to read it. Seeing the same structure across many problems is what turns proof-writing from guesswork into a reliable skill.

Do you cover measure theory and complex analysis as well?

Yes. Lebesgue measure and integration, abstract probability built on them, and complex analysis through Cauchy's theorem, the residue theorem and conformal mappings are all part of the work I teach, and they sit on this same page rather than a separate one.
