Homework Assignments and Announcements

Text:  Elementary Differential Equations and Boundary Value Problems, by Boyce and DiPrima,
            Sixth Edition, John Wiley & Sons, 1997.

Course Description:
Ordinary differential equations: first and second order equations, applications, Laplace transforms;
partial differential equations: partial derivatives, separation of variables, Fourier series, applications.
Chapters in Boyce & DiPrima: 2, 3, 6, 10.
Three hours lecture, one hour recitation.
Prerequisite: 21-122.
 

Exams:
There will be three 50 minute midsemester tests and a comprehensive final exam. No calculators will be permitted on the tests or on the final. Make-ups for the tests will only be given in case of a legitimate excuse and will be oral, in general. Permission to take a make-up can only be given by your instructor (not your TA). You will have one week from the day the tests are handed back to appeal your grade.

Homework:
There will be weekly homework assignments . Homework will be assigned on Mondays and collected  at the beginning of recitation the following week. Solutions to the homework will be available to you a week later. Late homework will not be accepted.
 

Grades:
Your course grade will be determined by the higher of the following two computations:
First computation:
0.15*(average of the homework)+ 0.6*(average of the three tests)+0.25*(grade on the final)
Second computation:
0.15*(average of homework)+ 0.5*(average of the two best tests)+0.35*(grade on the final)
