The official textbook adopted by the mathematics department for this course is
Fundamentals of Differential Equations and Boundary Value Problems – 7th edition by Nagle-Saff-Snider.
If you do not intend to use this book for any future mathematics courses, there are a number of lower cost options.
- Per the publishers web site, with – or without – boundary values, the 9th edition of Fundamental of Differential Equations consists of the first 10 chapters of the 7th edition of Fundamentals of Differential Equations and Boundary Value Problems and is suitable for this course. In the past this 9th edition has been available as an ebook, at reduced cost. See below.
- Either the 5th edition of the with boundary values version; or 7th edition without the boundary values will be supported. They are available used.
- An eversion of the text is also available: This course is participating in the UF All Access program. Login at the following website and Opt-In to gain access to your required course materials – https://www.bsd.ufl.edu/G1CO/IPay1f/start.aspx?TASK=INCLUDED – UF All Access will provide you with your required materials digitally at a reduced price and the ability to pay using your student account. This option will be available starting 1 week prior to the semester starting and ending 3 weeks after the first day of class.
- If you are unsure, during our first class meeting we will discuss the textbook options.
