I am trying self-study real analysis using Analysis I by Terence Tao . I came across some of the following:
Chapter 1: Introduction, page 8:
Limit interchange is always untrustworthy? (See Proposition $11.15 .3$ for an answer.
But there is no Proposition 11.15.3. Chapter 11 has only 10 sections.
Another example from chapter1 page 10:
Since $1 \neq 0,$ we thus seem to have shown that interchange of derivatives is untrustworthy. But are there any other circumstances in which the interchange of derivatives is legitimate? (See Theorem $11.37 .4$ and Exercise $11.37 .1$ for some answers.)
Again I could find neither Theorem 11.37.4 nor Exercise 11.37.1.
Am I missing something or is there is some mistake in the book?
As Nicholas Roberts pointed out, those are (wrong) references to parts of the second volume.
Example 1.2.8 is mentioned in Analysis II, Example 3.2.5.
Proposition which answers the question on the interchangeability of limits is indeed Proposition 3.3.3 in the second volume.
On the other hand, the question of Example 1.2.11 about interchangeability of partial derivatives is answered in Theorem 6.5.4 (Clairaut's theorem) and Exercise 6.5.1 again in Analysis II.
