Textbook
Elementary Differential Equations and
Boundary Value Problems
By W. E. Boyce and R. C. DiPrima, 9th
edition
Starting Autumn
2009, we are using the 9th edition of text by Boyce-DiPrima. In previous
quarters we used the 8th edition. Briefly, the changes related to our study are
(i)
Sections
3.4 through 3.9 have been renumbered 3.3 through 3.8, and
(ii)
a
few problems have been added, renumbered, or slightly changed.
You could choose
to use the old edition of the book. But for homework problems, you have to look
at a 9th edition (at the library, or a friend’s copy) or you could check
here for a
detailed list of changes between editions produced by Prof. Hart Smith.
