Any suggestions on a good text to use for teaching an introductory Real Analysis course? Specifically what have you found to be useful about the approach taken in specific texts?

Stephen Abbott, Understanding Analysis 


Look no further than Spivak's completely amazing Calculus. I have taught analysis courses from this book many times and learned many things in the process. One example is the wonderful "peak points" proof of the BolzanoWeierstrass theorem. The exercises are really good too. 


Rudin's Principles of Mathematical Analysis 


Anyone that thrusts baby Rudinas so many departments do,sadly,in an act of either callous indifference or elitist zealotismon beginning analysis students with no prior experience with rigor is committing an act of inhumanity against a fellow human being.Let's face it:Calculus just ain't what it used to be and Rudin is going to be a buzzkill for any but the best students. I personally have never liked Rudin even for good students. Rudin seems more interested in showing how clever he is then actually teaching students analysis.
My recommended texts:For average students,who have never seen proofs before,I strongly recommend Ross' Elementary Analysis:The Theory Of Calculus. It's gentle,complete and walks the reader through a careful presentation of calculus containing many steps that are usually omitted or left as an exercise. It can also be used for an honors calculus course:I've had friends that have used it for that purpose with great success. Spivak is a beautiful book at roughly the same level that'll work just as well.
More advanced,but I think well worth the effort, is Kenneth Hoffman's Analysis In Euclidean Space,which I reviewed for the MAA online a few months ago when Dover reissued it. It's an amazingly deep and complete text on normed linear spaces rather then metric or topological spaces and focuses on WHY things work in analysis as they do. This is the kind of book EVERYONE can learn something from and now that it's in Dover,there's no reason not to have it.
Lastly,for honor students on thier way to elite PHD programs,we now have a wonderful alternative to Rudin and I'm shocked no one's mentioned it at this thread yet:Charles Chapman Pugh's Real Mathematical Analysis,which developed out of the author's honors analysis courses at Berkeley. It's terse but written with crystal clarity and with hundreds of wellchosen pictures and hard exercises.Pugh has a real gift that's on display here:He knows exactly how many words it takes to clearly explain a conceptNOT ONE WORD MORE AND NOT ONE WORD LESS. I've never seen any author who does this as effectively as Pugh. The many,many pictures greatly assist him in this task:All of them serve some purpose,none are throwaways just to fill space. Even if it's just to make a joke(see the cornball pic in chapter one showing a Dedekind cut,ugh). 


I'm currently taking an introductory course in real analysis at the University of Glasgow. The set text is "Calculus" by Spivak. Totally deserving of its reputation. It's a great read with loads of exercises of varying degrees of difficulty. I also dip into a few others on a regular basis:



I'd recommend Hardy's Course of Pure Mathematics. Now in it's 101st year it still remains relevant to modern readers. It takes it bit longer to get to core of real analysis (e.g. limits, continuity, &c., &c.) than perhaps other similar texts do, which tends to make it more suitable as an introductory book, but there's enough there to engage those wanting explore the subjects in more detail. 


There are many good introductions to real analysis. My personal favorite is the UTM by Ken Ross. 


I recommend this book: Principles of Mathematical Analysis (by W.Rudin) By studying this book, you're gonna be able to achieve an accurate, as well as, an abstract view of concepts like continuity or RiemannStieltjes Integral ... By the way, Mathematical Analysis (by Tom M.Apostol) is a FANTASTIC book for one who wants to start the course. I personally taught this book once and the result was great. 


I was introduced to real analysis by Johnsonbaugh and Pfaffenberger's Foundations of Mathematical Analysis in my third year of undergrad, and I'd definitely recommend it for a course covering the basics of analysis. I'm not sure if it's still in print (that would certainly undermine it as a text!) but even if it isn't, it would make a great recommended resource or supplementary text. 


My favourite has always been Introduction to Analysis by Edward Gaughan. I just found out the AMS published the 5th edition. It contains, besides the standard calculus theorems, a very nice introduction to topology of the real line through the study of continuous functions. I can say that reading this book as a text in my undergrad course largely contributed to myself becoming an analyst. 


I'm using Analysis: With an Introduction to Proof by Steven Lay in my course right now, and from a student's perspective, it's been really good  clear explanations, and a tone of writing that doesn't seem too uptight. I can't speak to other books, but I've enjoyed this one so far! 


I think principle of analysis(rudin) and analysis (tom apostel) is good for you 


Binmore, Mathematical Analysis. He's at one of the London Universities (UCL I think). It's not flashy but it's very clean. The proofs are there; they're tidy and I think it's readable. I've used it for this kind of course myself. 


I do not know if it fits in the US curriculum, but to my mind the best book for mathematics undergraduates to learn analysis is Analysis I by Amann/Escher. I used to learn with it in my first 3 semester analysis courses (in Germany). I also quite liked Stephen Abbott's Understanding Analysis, but in hindsight it is not rigorous enough. Amann/Escher approach each subject from a very general view. For a novice this is most times a bit harder than comparable textbooks, but it pays off. The amazon preview of the English version by Chris Moore sums it up well. Analysis I is the first in a 3 volume series up to measure theory and Stokes' theorem. It fits quite nicely with the first 3 analysis courses at German/Austrian/Swiss universities. If nowadays a nonmath student comes in my office and is interested in real math, I recommend reading the first chapter of volume I about types of proof and elementary logic to get a first glimpse on how mathematics works. I can only recommend to have a look at this series. 


I'd recommend Analysis Now. EDIT: Now that the question has been clarified, I'll point out that this is too advanced for a first analysis course. 


I recommend Frank Morgan's Real Analysis for its clarity, the concise chapters, and good exercises. It's much more accessible than Rudin... while I loved learning with Rudin, I don't think it's for everyone. 


I'm not a fan of the Pfaffenberger text. For example, look at the proof of the chain rule. The proof sticks to the "derivative as slope" idea, and so has to consider the special case where one derivative is zero. This isn't very elegant, and causes confusion in what should be a straightforward proof  IMO when students are first being exposed to something as elementary as analysis, simplicity should be an overriding concern. Apostol, Buck and Bartle, those are texts that I like pretty well. Or the lecture notes used at the University of Alberta for their honours calculus sequence Math 117, 118, 217, 317 (available online)  pretty well based on Apostol. There's a few subtle issues going on here. Some departments view analysis as something people learn after they go through a servicelevel calculus sequence. Some departments treat calculus as part of an analysis sequence  ie students only see calculus through the eyes of analysis. What book you choose is largely determined by what path your department is comfortable with. 


We use Fundamental Ideas of Analysis from Michael Reed and have been very pleased. It's pretty nice as a 1 semester course for undergrads and has some nice lead ins to other areas where analysis tools are useful. 


Might not be a textbook but a very good supplement to a textbook would be the following book Yet Another Introduction to Analysis by Victor Bryant. As a prerequisite the book assumes knowledge of basic calculus and no more. Moreover, the book has solutions to all of the exercises. The following is the amazon link http://www.amazon.com/AnotherIntroductionAnalysisVictorBryant/dp/052138835X/ref=sr_1_2?ie=UTF8&qid=1417845189&sr=82&keywords=victor+bryant. This book may be a better starting point for some people.
