Thomas/Stewart + Apostol and Thomas/Stewart + Simmons would be overkill, I'd go with Thomas/Stewart + Spivak
By the way, I love these beautiful books, you should check it out :
Analysis by Its History by Ernst Hairer and Gerhard Wanner
Geometry by Its History by Alexander Ostermann and Gerhard Wanner
I'm starting to think (for me) this is the best option (Thomas or Stewart + Spivak). Mulling over things over the last few days or so, things are coming back to me quicker than I thought, and in the process of looking at these suggested and discussed books, a few things are becoming more apparent, or rather more clear to me. I will break things down a bit, as the thread did go off topic and diverge, but that's how my mind went too :) But in the end, as I said, with all the input, things are more clear to me now.
1. Initially, per the title of the original post, I was simply curious about Axler's two books which I've found are actually almost identical since. I'm using his "Precalculus" one as it's newer, and going through it pretty fast and nice. All good there. I could have gone with Lang's "Basic Mathematics", but had to decide, and just went with Axler. So that's that :)
2. The thread diverged off of Axler and precalculs textbooks (i.e. Lang's "Basic Mathematics", Simmons "Precalculus in a Nutshell", etc.), as math was coming back to me, and as I also knew I'd have to look at a calculus book to complement the ones used in the places I've applied to finish my degree (Thomas & Stewart). Once I looked the the syllabi and saw the schools used Thomas and/or Stewart, I looked them up on Amazon and other places, and as I said before, they seemed too computational and weak on theory. Too applied and simplistic for what I want. Not saying they are bad, just not for me. The trend towards those types of books is bad IMO, more on that later though. I gave an example of when I took a course that used a similar text at Cornell in the engineering department, and how using a text like that was not the best foundation for later more theory-based math courses. So I wanted to make sure I wouldn't be in the same boat.
3. After some more looking into the books, reading the replies here, in other threads, etc. I came to a few observations. There seem to be three main types/styles of calculus textbooks (in the US at least): The more "practical", applied, and computational books that seem to be revised every other year or so (Thomas, Stewart, etc.), the intermediate books that aim to strike a balance between computation/application and theory (Lang, Simmons, etc.), and the ones that lean more towards theory (Apostol, Spivak, etc.). I'm sure each has an audience, but for me, I find it a bit concerning that the first group is so dominant in colleges and universities in the US. Why? Because I see it as the simplification of content and a drive towards calculating instead of imagining. I believe that that first group should be eliminated, but it won't, and in fact the contrary - everything seems to be going in that direction. I think a book like Simmons' Calculus or Lang's Calculus (I've looked at them both) are perfectly fine for students to learn from, and strike that ideal balance between theory and applicability. Are they more challenging? Maybe, but so what? Isn't challenge part of it? I'm not saying calculus should be only for a select few, or made to be overly complicated, but to water it down is a sad state of affairs. But that's society today, particularly in the US. I suppose it comes down to many things, but a lack of a good high school curriculum across the country is hurting. My parents are from Eastern Europe. My father is a civil engineer. I have many friends from there that are not math majors, but like my father, took a ton of theoretical math courses that even math undergrads don't take in the US as part of their curriculum. They would have no issue with Spivak as a first course. But they are better prepared out of high school. They are used to theory and rigor. They are not put off by it, and IMO, they are better for it. They also had no choice in the matter, just as I don't. Which brings me to my final point and conclusion. I (like others) have no choice in what textbooks the college I'm attending will use for its math courses. For good or bad, I will have to use Thomas or Stewart. Now I KNOW that is not enough from prior experience. It just isn't. So I want to supplement that. I can't replace it, I can only supplement. And in the end, Spivak seems to be the best, as it's on the opposite end, and together a balance will be reached.
Anyway, this thread (and forum) have been helpful. I will try to contribute as I can in return. Although off topic, I hope it has been informative.
