This best-selling text by these well-known authors blends the traditional algebra problem solving skills with
the conceptual development and geometric visualization of a modern differential equations course that is essential
to science and engineering students. It reflects the new qualitative approach that is altering the learning of
elementary differential equations, including the wide availability of scientific computing environments like Maple,
Mathematica, and MATLAB. Its focus balances the traditional manual methods with the new computer-based methods
that illuminate qualitative phenomena and make accessible a wider range of more realistic applications. Seldom-used
topics have been trimmed and new topics added: it starts and ends with discussions of mathematical modeling of
real-world phenomena, evident in figures, examples, problems, and applications throughout the text.
