This is a Dover reprint of a book first published in 1990 in the Marcel Dekker Monographs and Textbooks in Pure and Applied Mathematics series. A "Telegraphic Review" appeared in the August 1991 issue of the American Mathematical Monthly:
Well-written text for a one-year undergraduate applied mathematics course. Prerequisites are calculus (three semesters), linear algebra, and basic physics. Includes necessary sections on differential equations. Gets to the applications quickly. MLR
Dover describes the new printing as a "corrected republication", but gives no specifics on what, if anything, was changed.
