Elementary Differential Equations and Boundary Value Problems, 10th edition is written from the viewpoint of the applied mathematician, whose interest in differential equations may sometimes be quite theoretical, sometimes intensely practical, and often somewhere in between. The book is written primarily for undergraduate students of mathematics, science, or engineering, who typically take a course on differential equations during their first or second year of study. The WebAssign component includes a complete online version of the text and a variety of interactive study aids. All of these rich resources are linked together in a dynamic and interactive environment for students.

Features

  • Links to the eBook within each problem are structured to support the way students work and provide them with superior just-in-time learning resources, and is available at a lower cost than the printed version.
  • Algorithmically generated solutions for all questions are available to students at the discretion of the instructor.
  • Guided Online (GO) Tutorials break the question up into segments to help students work through a problem and learn the concept.
  • WebAssign's patent-pending grading engine uses a series of robust grading routines customized for each exercise to accept all correct answers for the same complex question. Read our Answer Evaluation and Grading System report to learn more.

Questions Available within WebAssign

Most questions from this textbook are available in WebAssign. The online questions are identical to the textbook questions except for minor wording changes necessary for Web use. Whenever possible, variables, numbers, or words have been randomized so that each student receives a unique version of the question. This list is updated nightly.
