    Apostol definition of component interval

    Apostol in his "Mathematica Analysis" defines something called a "component interval". However, I cannot find it anywhere on google or in other books I have on analysis, and I really would like to see a picture of what he means.. Apostol's definition is that the component interval of an open...

    Apostol definition of interior point and open set

    S is a set such that S\subseteqRn point a is in S: a\inS The point "a" is an interior point of S if there is an open n-ball with center "a", all of whose points belong to S. ie., every interior point of S can be surrounded by an n-ball such that B(a)\subseteqS, where B(a) is the set of...

    Apostol: infinity as finite point

    I found a torrent online of Apostol's "Mathematical Analysis" 1st edition and I think I found a typo, or whoever scanned the book cut off the edge a bit... Apostol writes that the extended real number system R* is denoted by [-∞, +∞] while the regular real number system R is denoted by (-∞...

    Integrating (using partial fractions) Apostol Section 6.25 #25

    Homework Statement \int\frac{4x^5-1}{(x^5+x+1)^2}dx Homework Equations This is in the section on Partial Fractions. The main idea in this section was that you get the integral down to a sum integrals of the following forms: \int\frac{dx}{(x+a)^n} , \int \frac{x dx}{(x^2 + bx + c)^m} ...

    Does Apostol ever introduce Trig Substitutions ?

    Does Apostol ever introduce "Trig Substitutions"? I took Calculus before, but I am going over Apostol's Calculus Vol. 1 book. In section 5.7 he introduces Integration by Substitution, but never really discusses what was commonly referred to as "Trig Substitutions" in my Calc classes. For...

    Apostol volume 1 calc? what do I need

    Hi, I'm curious in learning calculus again but through a more rigorous fashion than plug and chug that I did last year. I'm trying to go slowly through Apostol's calculus but the way he's deriving the integral for a parabolic function x^2 is kinda troubling me. I'm fine until he reaches...

    Apostol vs Spivak: A Calculus Textbook Comparison

    Heard many people say that there are three good cal textbooks: the ones by Apostol, Spivak, and Courant. I own Apostol's and Spivak's. The major difference between the two is the degree of rigor and logical order, in which Apostol's apparently beats Spivak's, although Spivak's is far better than...

    Is Apostol's Calculus rigorous enough for my level of understanding?

    So, for instance, maybe Baby Rudin is the paradigm of "how to do it right" which includes proving stuff like Baire's Theorem. By "rigorous", I don't necessarily mean "Baby Rudin". On the other hand, Thomas and Finney does, in fact, have the formal definition of a limit, for instance, on p70 of...
