Basic Real Analysis. Math 3310, Section 1. Spring 2015

TuTh 2-3:15 pm, Monroe 111.

Text: Introduction to Analysis, fourth edition, William Wade.

Course outline

In this course we will rigorously introduce the main concepts of real analysis, including limits, continuity, differentiability, integrability and series, and prove the main theorems dealing with them (e.g. Intermediate Value Theorem, Mean Value Theorem and the Fundamental Theorem of Calculus). While all these topics and theorems are discussed in detail in Calculus I and II, not much is usually being said about their proofs. The goal of this course is not only (and not so much) to convince you that these theorems are indeed true, but rather to introduce you to the basic techniques used to prove those theorems and teach you how to apply those techniques to solve other problems. In particular, you will learn how to work with the ``epsilon-delta'' definition of the limit which is a fundamental skill for understanding any advanced topics in analysis. The plan is to cover the majority of material from Chapters 1-6 of Wade's book. I will assume basic familiarity with sets and functions (Section 1.5). You should read this section on your own in the first couple of weeks and ask me questions about unclear points.

A note on proofs. MATH 3310 is a proof-based course. Everything we discuss in class will be rigorously proved. More importantly, you are expected not only to understand proofs, but also to learn how to construct your own proofs and how to write proofs  (so that others can understand your argument). It is not expected that you have taken a proof-based course before MATH 3310. However, MATH 3310 will not include any lectures devoted specifically to proof writing; instead you will be expected to develop this skill gradually as we progress through the material. If you feel that you need a more detailed introduction to proof writing, I encourage you to take MATH 3000 (Transition to Higher Mathematics) before or concurrently with MATH 3310. MATH 3000 is offered this semester and will meet MWF 10-10:50am. An assessment exam will be administered at the beginning of the semester to help you make the decision about MATH 3000 .
