Elementary Differential Equations and Boundary Value Problems 11th edition PDF, like its predecessors, is written from the viewpoint of applied mathematicians, whose interest in differential equations may sometimes be quite theoretical, sometimes intensely practical, and often somewhere in between. While the general structure of the textbook remains unchanged, some notable changes have been made to improve the clarity and readability of basic material about differential equations and their applications. The authors have sought to combine a sound and accurate (but not abstract) exposition of the elementary theory of differential equations with considerable material on methods of solution, analysis, and approximation that have proved useful in a wide variety of applications. In addition to expanded explanations, the 11th edition includes some new problems, updated figures and real examples to help motivate math students.
The program is primarily intended for undergraduate college students of mathematics, engineering or science, who typically take a course on differential equations during their first or second year of study. The main prerequisite for engaging with the program is a working knowledge of calculus, gained from a normal two or three semester course sequence or its equivalent. Some familiarity with matrices will also be helpful in the chapters on systems of differential equations.
