MTH 244/2
Differential Equations
Fall 2007/URI
Text: Ordinary Differential Equations by Finizio and Ladas, Simon and Schuster, Third Edition
Exams and Grading: Your grade will be based on three tests, a final exam, quizzes and Maple projects as follows:
Three tests at 100 points each 
300 points 
Final exam 
150 points 
Quizzes 
150 points 
Maple 
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 and Scientific Notebook and online programs that can be found on Internet. We will give a brief introduction to such resources. Some Maple notebooks 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, biomedical sciences, and economics, as well as leading 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. 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 series
Numerical solutions of ordinary differential equations
