Patrick M. Fitzpatrick's "Advanced Calculus, Second Edition" is widely used in upper-division undergraduate and beginning graduate courses in mathematics. Despite careful editing and proofreading, some errors inevitably make it into publication. This page serves as a centralized resource for known errata in this valuable textbook.
Errata are corrections to errors found in a book after publication. In mathematics textbooks, these can range from typographical errors and misprints to substantial mathematical mistakes that could affect understanding. Keeping track of errata is particularly important in mathematics texts, as even small errors can lead to confusion or misdirected learning.
Current text: "Let f: be defined by f(x) = x + 1 for x ."
Correction: The domain statement is redundant with the earlier declaration. Should read: "Let f: be defined by f(x) = x + 1."
Current text: "Consider the function f: [0,1] defined by f(x) = 1/n for x = 1/n where n is a positive integer."
Correction: Should specify that f(x) = 0 for x not of the form 1/n. Complete definition should read: "Consider the function f: [0,1] defined by f(x) = 1/n for x = 1/n where n is a positive integer, and f(x) = 0 otherwise."
Current text: "A function f: D is called uniformly continuous on D if for every > 0 there exists > 0 such that if x,y D and |x-y| < , then |f(x)-f(y)| < ."
Correction: The definition is correct, but the notation could be clearer. Should read: "A function f: D is called uniformly continuous on D if for every > 0 there exists > 0 such that for all x,y D with |x-y| < , we have |f(x)-f(y)| < ."
Current text: "If f: [a,b] is continuous on [a,b] and differentiable on (a,b), then there exists c (a,b) such that f'(c) = (f(b)-f(a))/(b-a)."
Correction: The theorem statement is correct, but the figure illustrating it is incorrectly labeled. Point c in the figure should correspond to f'(c), not f''(c) as shown.
Current text: "Consider the function f(x,y) = xy + xy - 2xy + x - y."
Correction: In the computation of the gradient, the partial derivative with respect to y is incorrectly shown as f/y = x + 2xy - 2x - 1. The correct partial derivative is f/y = x + 2xy - 2x - 1.
Current text: "Prove that if f: [0,1] [0,1] is continuous, then there exists c [0,1] such that f(c) = c."
Correction: The statement is correct, but the hint provided is misleading. The hint should suggest applying the intermediate value property to the function g(x) = f(x) - x, not analyzing critical points as currently suggested.
Current text: "Consider the sequence {x_n} defined by x_1 = 1 and x_{n+1} = sqrt(2 + x_n) for all n 1."
Correction: In the calculation of the limit, it is incorrectly assumed that the sequence is increasing without proof. The complete argument should first demonstrate that the sequence is monotone (using induction) before applying the Monotone Convergence Theorem.
Minor typographical errors in examples 1.3 and 1.5. These do not affect the mathematical content.

Page 43: Incomplete function definition in Example 3.2 (see detailed entry above).
Page 78: Notation clarity issue in Definition 4.7 (see detailed entry above).
Page 112: Incorrect labeling in accompanying figure for Theorem 5.10 (see detailed entry above).
Minor formatting issues in displayed formulas on pages 134-136.
Page 156: Partial derivative notation inconsistent in Example 7.4 (see detailed entry above).
Additional errors have been reported in Exercise 9.14 and Example 11.3 (see detailed entries above). Otherwise, no other significant errata reported at this time.

If in doubt, reference both the page number and the chapter/section for clarity.
"Advanced Calculus, Second Edition" by Patrick M. Fitzpatrick remains a highly respected text for rigorous study of calculus at the advanced level. While the errata listed above should be noted, they represent a very small fraction of the content and do not significantly detract from the pedagogical value of this textbook. These errors will likely be corrected in future printings or editions.
We encourage readers to use this page as a reference while studying, and to report any additional errors they may discover. The ongoing collaboration between authors, publishers, and readers in identifying and correcting errata strengthens mathematical education for everyone.
