MTH 244/2
Differential Equations
Spring 2010/URI

TextOrdinary Differential Equations by Finizio and Ladas, Simon and Schuster, Third Edition

Exams and Grading: Your grade will be based on two tests, a final exam, quizzes and Maple projects as follows:

 Two tests at 150 points each 300 points Final exam 200 points Quizzes 100 points Two Maple Assignments 100 points Total 700 points

Calculators and Computers: As in Calculus Courses you will need a programmable graphing calculator. You are encouraged to use the CAS (computer algebra system) such as Maple, Livemath, and Scientific Notebook and online programs that can be found on Internet. We will give a brief introduction to such resources. All Maple notebooks needed will be provided and demonstrated in the class.

Course Description: In MTH 244 we study ordinary differential equations in greater details than in the calculus courses. This subject has wide applications in the physical sciences, engineering, bio-medical sciences, and economics.  Ordinary Differential Equations lead to many advanced areas of mathematics itself. You will find that there are new algebraic ideas to master.

The homework problems are the core of this course. An important purpose of the problems is to make you think through and master the ideas of the subject so that you can confidently apply your knowledge in new situations. You will learn a great deal from honest hard work on a problem, even if you don't succeed in solving it. Read the text material before working on the problems.
The exams will reflect the variety of the homework problems, quizzes and problems solved in the class. It is important that you give these problems adequate time and effort.

The topics that will be covered are:

Exact solutions of first order differential equations (homogeneous, linear, Bernoulli, differential equations with total differential)

Existence and uniqueness theorems for differential equations

Linear differential equations – general theory

Systems of linear differential equations

Laplace transform and applications in solving linear differential equations

Solving linear differential equations with method of series

Numerical solutions of  ordinary differential equations
