Textbook in PDF format

Ordinary Differential Equations: An Introduction to the Fundamentals is a rigorous yet remarkably accessible textbook ideal for an introductory course in ordinary differential equations. Providing a useful resource both in and out of the classroom, the text:
• Employs a unique expository style that explains the how and why of each topic covered
• Allows for a flexible presentation based on instructor preference and student ability
• Supports all claims with clear and solid proofs
• Includes material rarely found in introductory texts
Ordinary Differential Equations: An Introduction to the Fundamentals also includes access to an author-maintained website featuring detailed solutions and a wealth of bonus material. Use of a math software package that can do symbolic calculations, graphing, and so forth, such as Maple™ or Mathematica, is highly recommended, but not required
