This concise text offers undergraduates in mathematics and science a
thorough and systematic first course in elementary differential
equations. Presuming a knowledge of basic calculus, the book first
reviews the mathematical essentials required to master the materials to
be presented.
The next four chapters take up linear equations, those
of the first order and those with constant coefficients, variable
coefficients, and regular singular points. The last two chapters address
the existence and uniqueness of solutions to both first order equations
and to systems and
n-th order equations.
Throughout the book,
the author carries the theory far enough to include the statements and
proofs of the simpler existence and uniqueness theorems. Dr. Coddington,
who has taught at MIT, Princeton, and UCLA, has included many exercises
designed to develop the student's technique in solving equations. He
has also included problems (with answers) selected to sharpen
understanding of the mathematical structure of the subject, and to
introduce a variety of relevant topics not covered in the text, e.g.
stability, equations with periodic coefficients, and boundary value
problems.
