| Text: | Ordinary Differential Equations by W. A. Adkins and M. G. Davidson |
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:
The Final is on Thursday, July 27, 4:00-6:00.
| GRADE | POINTS |
| A+ | 435 - 450 |
| A | 420<435 |
| A- | 405<420 |
| B+ | 390<405 |
| B | 375<390 |
| B- | 360<375 |
| C+ | 345 < 360 |
| C | 330<345 |
| C- | 315<330 |
| D+ | 300<315 |
| D | 285<300 |
| D- | 270<285 |
| F | <270 |
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.
