SUBJECT:
Differential equations are extensively used as a tool for modeling diverse phenomena ranging from population growth to elementary particles. The purpose of this course is three-fold: firstly, to familiarize yourself with various types of differential equations and master the basic solution techniques; secondly, to see how you can use differential equations in studying real-world systems; thirdly, to get an idea of what to do when you cannot solve the equation. We'll cover most of the contents of Chapters 1 - 6.

CONTENTS:
The class will follow the outline below, touching on each major topic in a depth that will be determined by the pace of the class. The dates are tentative and are not guaranteed.

GRADING:
In class Midterm Test (on Ch. 1-3) - 30%,
In class Final test (on Ch. 4-6) - 30%.
Computer Project - 10% extra credit,
In class 3 Quizzes(best 2 out of 3)- 40%.

No quizz make-ups accepted. Exams make-ups only with a very strong justification. All quizzes and exams are in class, open book/notes, no electronic devices of any kind (including, but not limited to mobil phones, calculators, CD-players, computers). Exams and quizzes may be in a multiple choice form.

The following distribution of grades is used:
A+ 95-100%, A 90-95%, A- 85-90%
B+ 80-85%, B 75-80%, B- 70-75%
C+ 65-70%, C 60-65%, C- 55-60%
D+ 50-55%, D 45-50%, D- 40-45%

COMPUTING:
Individual projects will be accepted in Matlab only. MATLAB can link executable files, it has graphics already built in and it is an interpretive language originally developed to handle mathematical problems. The students are invited to use the MERC lab where computers with MATLAB are available. Students may also consider getting their own individual student version of MATLAB at MATLAB & Simulink Student Version Release 14 Web page, but it is not required for the class.

ATTENDANCE AND HOMEWORK:
Punctual attendance and homework fulfilment are expected of all students. Students are expected to solve most of the odd numbered problems from the text. Homework problems will not be collected unless by students request.
