## MAT 320 Introduction to Analysis Fall, 1996

NOTE (11/15/96): See Revised Syllabus; Optional Second Midterm.

This figure from Isaac Newton's Principia Mathematica (1686) illustrates his Lemma II which states, in modern terminology, that for a monotonic function the left- and right-hand sums have the same limit, which is the area under the curve. I have edited out some lines and notation referring to a different lemma. Press here to see the full Latin text of Lemma and Proof, with a translation into English. Press here for an animated version of Newton's diagram, due to Stony Brook student Vladimir Livshits. Clicking on the difference rectangles makes them slide into a single column.

This edition of the book is being distributed to us for free. In return, please mark carefully in your copy any misprints or errors you find, as well as any passages you find hard to understand, and please turn in your books at the end of the term (you can have them back eventually). Wiley is giving us some money we can use for a pizza party at the end of classes.

Here is a link to an Interactive Real Analysis page under development at Seton Hall University. (``Interactive Real Analysis is an online, interactive textbook for Real Analysis or Advanced Calculus in one real variable. It deals with sets, sequences, series, continuity, differentiability, integrability (Riemann and Lebesgue), topology, and more.'')

Homework will be collected each Thursday.

I have two main goals in this course. First to acquaint you with the mathematical foundations of the Calculus and at the same time to introduce you to some of the many mathematical phenomena related to the Calculus. Second is to train you in the construction and analysis of mathematical proofs. I will try to assign each week at least one homework exercise that involves making up a proof.

Format for Proofs. Please follow the following format in submitting proofs. This will allow you to assemble them into a portfolio at the end of the semester.

• Each proof should be on a page or pages by itself. Put name, course number and date due at the top of the page.
• Begin with words of introduction (only if necessary). For example the Catalan number exercise could start with "The Catalan numbers are defined by C(1)=1, C(2)=2 and the recursion relation ......" The statement to be proved should be prefaced by the words "Theorem," "Proposition," etc., whatever you feel is appropriate.
• The proof should begin with: "Proof." and end with "QED" or "which completes the proof" (if appropriate) or some such words to show that the argument is over.
• The text of the proof must be in clear, correct, grammatical English. I will instruct the grader to return for correction all homework that does not meet this requirement.
• The argument must be presented in enough detail so that you could give it to one of your classmates to read.
• Last but not least, the argument must be complete and mathematically correct!!

Disabilities. If you have a physical, psychological, medical or learning disability that may impact on your ability to carry out assigned course work, I would urge that you contact the staff in the Disabled Student Services office (DSS), Room 133 Humanities, 632-6748/TDD. DSS will review your concerns and determine, with you, what accommodations are necessary and appropriate. All information and documentation of disability is confidential.
