Course Objectives:

An ability to solve differential equations is crucial to an understanding of problems arising in all branches of science, social science and business. The aim of this course is for the student to acquire the knowledge and techniques necessary to solve ordinary differential equations, and also for the student to gain an understanding of the breadth of applications of differential equations to real-world problems.

One of the tools necessary for the solution of differential equations is power series and this course begins with a treatment of sequences and series, with an emphasis on power series and Taylor series. Another important application of infinite series is in evaluating nonelementary integrals, as we shall see.

 

Prerequisites:

Mathematics 230 (Linear Algebra) and Mathematics 270 (Calculus 3)

 

Textbooks:

 Thomas’ Calculus by Finney, Weir and Giordano (10th edition, Addison, Wesley, Longman)

A First Course in Differential Equations by Dennis G.Zill (The Classic Fifth Edition, Brooks Cole)

Chapters covered:

Thomas:  Chapter 8

Zill: Chapters 1-6

 

Major Topics:

1.      Infinite sequences and series, power series, Taylor series

2.      First order ordinary differential equations: separable, homogeneous, exact, integrating factors. Applications.

3.      Higher order ordinary differential equations: homogeneous, nonhomogeneous, undetermined coefficients. Applications.

4.      Variable coefficient differential equations: power series solutions

 

Course Requirements:

There will be a test at the end of each chapter. You will be given at least 1 week's notice of each test date. The tests will all have equal value and will together count for 75% of the final grade. Homework assignments count for 20% with attendance and class participation counting for the remaining 5%.

 

Attendance:

I will take attendance at the beginning of each class. Should you be unable to attend I expect you to call me and explain your absence. Excessive absence or frequent lateness may affect your grade. More than 8 absences will result in a course grade of F.

 

Make-up Examinations:

These will not be given except in extraordinary circumstances and with prior approval.

To arrange for a make-up you must call me or see me before the scheduled examination.

Missed examinations automatically result in a grade of 0.

 

Homework:

Homework will be assigned weekly and, unless otherwise stated, will be due one week from the day that it is assigned. Late homework will be accepted for credit only if you obtain prior approval. No homework will be accepted more than 1 class period late.
