All known misprints in the January 99 edition have been corrected.

### Misprints in the August 1999 edition of "Linearity"

• Exercise 3.5.8, page 128: The numerator in the "Given" differential equation is xy2 + 1 (not xy1 + 1).
• Exercise 6.1.9, page 244: The relevant exercise is 3.3.2, not 3.1.2.
• Page 250, text line 4 from bottom: The "easy to see" equation applies to the perpendicular part of the vector, not the parallel part.
• Page 254, last line: The norm on the left should be squared.
• Page 268, lines 6 and 4 from bottom; page 269, line 7 from top: The integrand of the line integral is F . dx (not F . x ).
Incidentally, in response to popular demand, in the published version the vector x will be changed to vector r whenever its components are, or probably would be, named (x, y, z).
• Page 274, line 6 from bottom: Remove the factor 1/2 on the left. (Then all members of the equation equal twice the antisymmetric part of the Jacobian.)
• Page 288, line 11, and page 289, line 7: The lower limit of integration is -1, not 0.
• Page 308, line 5 from bottom: Remove the factor sin(theta) from the cylinder formula.
• Page 311, Example 1, lines 10 and 4 from bottom: 36 (in two places) and 108 should be multiplied by pi.
• Exercise 7.6.17, page 342: n = 2 should be p = 2.
• Page 356, line 5: (U|E) should be (U|I).
• Page 365, line 6: The reference to Bowen and Wang in Sec. 5.4 disappeared in some earlier revision. The book is
R. M. Bowen and C.-C. Wang, Introduction to Vectors and Tensors, Vol. 1 (Plenum, 1976); see Theorem 18.3.

A section on the history of linear algebra has been added to the final preliminary edition (January 2000) as Sec. 8.3. The published version will show some significant formatting changes and a very few changes in content, notably in the exercises in Sec. 8.1. You can view that version of Chapter 8 here.
