Thank you, Mr. verty! My plan is to finish Lang's A First Course in Calculus and Spivak's Calculus over this summer. My next mathematics course is a two-semester course called "Multivariable Calculus and Linear Algebra", which requires the second volume of Apostol. I am planning to purchase Lang's Multivariable Calculus and use it as a supplement to the APostol since Spivak only covers the single-variable calculus. I looked at Simmons' Calculus and Analytical Geometry, but I feel like it is not as good as Lang's. Do I need to purchase Apostol's first volume (single-variable) if I already have Spivak? Do I need to complete the first volume of Apostol in order to understand the second volume of his calculus textbook? Does anyone read the book called "How to Prove It" by Daniel Velleman? I am also planning to purchase the linear algebra textbook(s) to supplement the linear algebra portion of my course (I mentioned that the required textbook is Apostol's second volume)...does anyone know a good linear algebra that is easy to read and not rigorous as Apostol? I saw the linear algebra book wrote by Serge Lang, but I do not know if that is a good book..
I sincerely apologize for keep asking many questions regarding to the mathematics textbook, but I want to make sure I bought the right textbooks.
Whew! One busy summer! So let me try to summarize at least what I understand so far, and what I would do in your situation given I understand it correctly:
1. You have taken Calculus I & II using Stewart's book, which you were fine with, but felt it/the course wasn't as rigorous or in-depth as you'd like and think you will need for further studies.
2. You are looking for a good book to self-study/review Calc I & II from over the summer in a more in-depth/proof-based way than you did in school with Stewart.
3. You looked at Spivak and were surprised to see how tough it was.
4. You decided to use Lang's "A First Course in Calculus" then, but also got Spivak even though you admitted it will take you over 2 months to just read the book, never mind do the problems.
5. You want to ensure you are getting the best book(s) and not missing out on anything.
6. You will be taking a 2 semester course on Linear Algebra & Multivariable Calculus in the fall, which will use Apostol's 2nd volume.
7. You also want to get a head start on linear algebra this summer as well.
This is a summary of what I got out of your posts thus far - the facts as it were.
If these "facts" are true, then what I would say (and actually do myself if in your shoes), is get Apostol Vol. 1, and use that to review and go more in-depth for Calc I & II and to get an intro to linear algebra (the last 4 chapters are linear algebra in Vol. 1). Why complicate things with Lang, Spivak, etc.? You may like those, and they are good books, but if you are going into a course that will be using Apostol Vol. 2 for more linear algebra and multivariable calculus, then why not get familiar with Apostol by reviewing single-variable calculus and intro linear algebra with Apostol Vol. 1? For me, it makes perfect sense to go this route and just stick with Apostol Vol. 1 over the next few months. It will certainly take you pretty in-depth on Calc I & II and introduce you to linear algebra. And you will be perfectly lined up to start your course that uses Vol. 2!
You don't want to go nuts with 5 books over one summer! It would be better I think to get the most out of Apostol Vol. 1 instead of using 5 books. Just my 2 cents and what I would do.
