Text: | by W. A. Adkins and M. G. Davidson Ordinary Differential Equations |

- The book is available at LSU Bookstore. There is also an optional solutions manual that can be purchased at the same place. This manual contains solutions to many, but not all, exercises in the text.
- An electronic version of the text (PDF file) can be downloaded here: Math 2065 text,
- and the solution manual can be found here: Math 2065 Solution Manual.
- Supplemental Materials from the webpage of Prof. Adkins:
- Function Properties is a sheet with commonly used properties of the exponential, logarithm and trigonometric functions.
- Integral Table is a brief table of integrals with which you should be familiar from your calculus class.
- A Primer on Matrices. This short primer contains most of the material on matrices that will be needed for the course.
- Old tests and solutions (Scroll all the way down).
- Some extra information like corrections and solution manuals can be found at Professor Mark Davidson's webpage

Each student is responsible for ensuring that he or she has access to and functioning LSU email address and Moodle account. Email will ** only ** be sent to leu-email addresses. Important class information and grades will be posted on Moodle.

This is an introductory course in ordinary differential equations with a particular emphasis on linear differential equations. A nuance of the present course is an early introduction of the Laplace transform into the theory, and then subsequently using the Laplace transform to extract much of the basic information about constant coefficient linear ordinary differential equations in an expedited manner. We will cover most (but not all sections) of the text.

There will be three tests in class during the semester:

- Monday, June 19
- Friday, June 30
- Tuesday, July 18

The Final is on ** Thursday, July 27, 4:00-6:00**.

- Tests: 100 each. Total: 500.
- Final: 150.
- Total points:
**450**.

Absence on a Test, or Final without excuse makes automatically 0 points. Only serious and verifiable excuses will be respected. Please inform me before the test

Students may use a basic scientific calculator similar to a TI-30 in an exam. Students may not use calculators capable of graphing, symbolic manipulation, solving equations, or symbolically calculating derivatives or integrals.

Cell phones, and other electronic devices are forbidden. Cell phones must be shut off (not merely silenced) and may not be accessed during an exam.

Homework is assigned daily, but it is not collected or graded. Doing the homework exercises as they are
assigned is the best strategy for a successful completion of the course. I will work out some of the problems (2 or so) in class ** the
next day after each section was covered in class.**
