Overview.

In Introduction to Ordinary Differential Equations, we shall be using your background in science and engineering and your previous knowledge of algebra and calculus to consider the practical questions in ordinary differential equations. In single variable calculus, we use techniques of integrations that allow us to determine

yÕ(x) = f(x)  with y(a) = c

by integration.

 

The term ordinary indicates that we will be consider y along with its derivatives yÕ, yÕÕ, É  as functions of a single variable x. We can write this differential equation as

F(x, y(x) , yÕ(x) , yÕÕ(x), É , y(n)(x)) = 0.

 

The highest derivative in this expression, n, is called the order of the differential equation. Ordinary differential equations are used to model and analyze any situation in which the change in some function depends on the value of the function. These models can be seen in mechanical motion, dynamical properties of electrical circuits (physics), the motion of celestial bodies (astronomy), chemical reactions (chemistry), changes in land forms (geology), heat transfer and thermodynamics (mechanical engineering), properties of materials (material science and optics), population models (ecology and epidemiology), and the flow of capital and goods (economics)

 

 

Day-to-Day Operations. 

The class meets daily from 11:00 AM to 12:45 PM in room 210 of Biological Sciences West Building . The textbook is Fundamentals of Differential Equations (Eighth Edition) by R. Nagle, E. Saff, and A. Snider.  The course will cover the majority of chapters 1, 2, 4, 5, 8, and 9. The exact schedule of topics and assignments are given in the course syllabus. 

 

With the intensity of a summer session course and the need to develop solutions techniques and strategies for interpretation of the solutions to ordinary differential equations, we will hold office hours and problem sessions in the Slot Canyon CafŽ inside the Environmental and Natural Resources Building 2 both before and after class.

Evaluation of Students.

Students will be evaluated through homework exercises, group projects, and exams. Homework will be due approximately 2 to 3 times per week. Group projects will generally completed in groups of two. They are described at the end of each chapter of the textbook.

 

The grading scheme is

Grades will be given on the usual scale A is 90%-100%, B is 80%-89%, C is 70%-79%, D is 60%-69%, and E is below 60%. The instructors may move these cutoff values down. Any grading disputes must be addressed within one week after an exam or homework has been returned. If you fail to complete the course due to circumstances unforeseen, then you may qualify for a grade of I,  ÒincompleteÓ in accordance with University Policy.

 

Students should take the time to become familiar with policies and codes of the University, notably the academic integrity policy and student code of conduct. Student with special needs should contact SALT - Strategic Alternative Learning Techniques Center or the Disability Resources Center.

 

Best wishes to you for a good summer in this course and in all your other activities.
