PEI Math 521K

It tests rigorous real analysis: constructing epsilon-delta proofs, applying the mean value theorems, judging convergence of series and function sequences, reasoning about compactness in metric spaces, and using the inverse and implicit function theorems. Computation alone earns little; the marks come from correct definitions, valid logic, and complete justifications.

Substantially harder for most candidates. Computational exams reward procedure; this one rewards precision of language. A single misquantified variable or an unjustified interchange of limits can void a proof. Students who memorise theorem statements but cannot reproduce proofs usually find the exam difficult.

The official body sets the current format, duration, and any permitted materials, and these can change between terms. Check with the UPEI Department of Mathematics and Statistics or your course instructor for the authoritative details before you plan your preparation.

Retake rules and the passing threshold are institutional policies, not fixed facts. The university publishes the current regulations, so consult UPEI directly rather than relying on secondhand accounts. Plan on passing first time; retake windows may not align with your programme requirements.

Start with the real number system, supremum and infimum, and logic, because every later proof depends on them. Then sequences and series, continuity and uniform continuity, differentiation, and integration. Leave function sequences, metric spaces, and multivariable theorems for last, since they reuse all the earlier machinery.

Using a theorem without checking its hypotheses, confusing pointwise with uniform convergence, treating compactness as a synonym for closed and bounded outside R^n, and writing prose where a quantified statement is needed. Another frequent error is proving a converse that was never asked for while omitting the direction requested.

Close the book and write definitions and major theorem proofs from memory, then compare word by word with your text. For problem sets, write full solutions under time pressure, and afterwards mark your own work against the rubric: hypotheses stated, quantifiers correct, conclusion reached. Keep an error log of recurring mistakes.

Not all of them, but you should be able to reproduce the central results, including completeness arguments, the mean value theorems, uniform convergence tests, and the inverse and implicit function theorems. For the rest, know precise statements and hypotheses, and be able to reconstruct the main idea when asked.
