Course Description and Prerequisites:
Introduction to ordinary differential equations. First and second
order linear differential equations, systems of linear differential
equations, Laplace transform, numerical methods, applications. To be
successful in the class, you should have a good working knowledge of
Calculus (Math 131, Math 132 and perhaps Math 233) and bit of Linear
Algebra (Math 235).
Required Text:
Elementary Differential Equations, 11th Edition (2017) by William
E. Boyce, Richard C. DiPrima & Douglas B. Meade.
An electronic copy of the textbook is integrated in the homework
system Wiley-Plus that we will use for the class. When setting-up your
account with Wiley-Plus there will be an option to purchase a hard
copy of the book for a (small) extra-fee.
Step 1: Go
to Wiley
web site (special link for UMass) to purchase the eTextbook +
Wiley-Plus registration code at the special price of $50. For an extra
fee of $25 you can also purchase a hard copy of the book. Students
MUST use their discount code here; if you purchase on any other link,
you will not get the discount.
Create an account (be sure to use your UMASS CAMPUS EMAIL as your
username, type in the exactly same first name and last name as you
used on SPIRE) and sign-up for your class using the discount code you
purchased at the above site. Please make sure to sign up for the
correct section.
Go to
the Wiley-Plus
web site to sign in and complete homework.
Homework Topic Schedule:
Please see

chair's webpage for further schedule details and written homework, the first of which will be drawn from the midterm practice problems: please start on these now!
Try solving all 25 of them before you take the midterm exam next Thursday at 7PM 22 February in ISB 135 (you may also want to bring a calculator to the exam).
And please write up and turn in the following
5 midterm
practice problems - 3, 8, 9,
23, 24 -
as homework at the beginning of class on Thursday 22 February -
this is the only time and place this homework will be accepted!
(Here are
the course
chair's solutions - no guarantees! ;-)
The second
written homework - please turn in the EVEN problems
only - is due at the beginning of class on Thursday 12
April - as before, this is the only time and place this
homework will be accepted! (Later, I'll email you all the
solution sketches - but again, no guarantees! ;-)
The
third
written homework - please do and turn in ALL the
problems - is due at the beginning of class on Tuesday 1
May - this is the only time and place this homework
will be accepted!
You should attempt all the
final
written homework BEFORE the final exam. Problems 1, 2, 8, 13, 15, 16 & 18 may be submitted for EXTRA CREDIT before noon
on Monday 7 May by slipping the completed - and stapled!!! -
problem set under my office (LGRT 1435G) door.
Grading:
Course grades will be based in roughly equal parts on the homework
(on-line
and written),
on the midterm (7-9PM Th 22 Feb), and on the final exam (TBA). Please
see
the course
chair's webpage for further grading details.
Exam details:
The Midterm Exam is scheduled for 7PM Thursday 22 February 2018 in ISB
135. You may want to bring (and use) a calculator!
All students are expected to take the
exam at the regular time and place, unless they have contacted both me
and the course chair at least 10 days in advance about qualifying (because of another exam
with a higher SPIRE priority) for the make-up exam (7PM Friday 23
February in LGRT 219).
The Final Exam is now scheduled on SPIRE for 10:30AM Friday 4 May 2018
in Mahar 108. Please check SPIRE for any updates!
All students are expected to take the final exam at the regular
time and place, unless they have contacted both me and the
course chair at least 2 weeks in advance about qualifying
for any special accomodations (for instance, the make-up exam is 2-4PM
Monday 7 May in LGRT 219, and you need to email both me and the
course chair with the reason you might qualify). Furthermore,
it is the student's responsibility to contact Disability
Services by Wednesday 18 April to arrange taking the
final exam there.
Students have asked "Will there be a table of Laplace Transforms on
the exam sheet?" The answer: of course!
Have a great summer!!!!!!
