Instructive Real Analysis

[Tom Mattson]

Has anyone ever seen this? It's an interactive online textbook in analysis in a single real variable. As an undergrad, I wussed out and took Advanced Calculus instead of Analysis, and this is a subject I've been meaning to learn. Is anyone interested in going through this?

It looks like it could serve as a springboard to get into more advanced books that I've found online.

This will seem like a really silly question but...

As long as we're sticking to real functions of a single variable (and not delving into abstract spaces and measures), what's the difference? (I'm beginning to suspect that my teacher taught us both in my advanced calc courses)

i think "analysis" has to have the word "real" in front to be compared to advanced calculus.

otherwise, things like metric spaces are included in the subject.

To a mathematician, the word analysis by itself means functions of a complex variable. Other discplines mean other things by it. The Freudians...

I talked with a coworker, and he confirmed my suspicions; my advanced calc class did indeed delve a decent bit into real analysis, which is the source of my confusion!

i think the term "function theory" is what is used for complex analysis.

not all mathematicians have the same definition of "analysis."

OK, sorry I took so long to get back to you. As far as I know, the thing that differentiates Advanced Calculus from Real Analysis is theorem proving. In my Adv Calc class, we covered multivariable calculus (differential and integral), vector calculus, calculus of variations, and a very little bit of PDEs. We learned nothing of spaces, measures, Lebesgue integration, etc.
