Introduction to Real Analysis; the real number system, limits, continuity, the mean value and Taylor's theorems and applications, Riemann integration and improper integrals.
Grading Policy: 11 Quizes: 5% each... Midterm Exam: 15%...
THE QUIZES COUNT MORE TOWARDS THE GRADE THAN EITHER OF THE EXAMS!
Quizes will be in the first 10 minutes of class on Mondays.
Students must submit completed *ed homework from the prior week
in order to begin a quiz and that homework will be part of the score.
Students who miss quizes because they
are absent, late or have not completed the homework will receive a 0 on
that quiz. There will be no make up quizes. There is one extra quiz.
Note that a quiz may contain proofs and the proofs should be written
in a two column format with statements and justifications. Very similar
proofs will be on the homework that is required to take the quiz.
If you are unsure of the proof of a problem, you may write a question
mark next to the step you are unsure of.
In the following syllabus, homework is written below the lesson
when it is assigned and *ed problems are collected on the days

Mon 12/15: Review for Final
The final will have two sections: short answers and
proofs. In the proof section there will be two proofs:
In the short answer section, other proving techniques
will be tested including
- a proof that a function is continuous at a point
- a proof that a sequence converges.
In order to complete this section you will need to know the statements of
all the important theorems and definitions we've learned this semester
including sup, inf, bound, limit, bounded increasing sequences converge,
sandwich lemma, subsequences of bounded sequences converge, Cauchy sequences,
theorems about these, continuity, theorems about this,
differentiation, mean value theorem, Rolle's
theorem, Riemann integration of continuous functions, theorems
about integration, improper integrals, series, convergence
tests including comparison, ratio, root and alternating series tests,
Taylor series, radius of convergence, uniform convergence. You will
also need working knowledge of these concepts in the sense that you
must be able to find the limit of various given
sequences, the sup and inf of various sets and functions, the Taylor
series for a given function and give its radius of convergence.
- write the first line of a proof by contradiction,
- outline a proof by induction
- suggest theorems that might be relevant to prove a statement
- fill in the justifications for a proof about integrals
- find limits, sups and infs without proof
- find taylor series and verify convergence of the series
