MA 345 Students,

At this point, most of you should have finished
Assignment 15 (variation of parameters).  The
solutions will be posted on Tuesday, March 24.

In the meantime, it's time to start on Laplace
transforms.  Begin by watching the following
excellent introductory video on the subject:

Video - Introduction to Laplace transforms

Next, read the following notes on Laplace
transforms:

Calculation of Laplace transforms
Calculation of inverse Laplace transforms

These notes will help you prepare for
Assignment 16.

I have made some changes to the homework
schedule.  Please check the following link
to the new schedule:

Revised schedule

It's now clear that we will not be meeting
face-to-face for any other classes this term.
I have decided that the remaining exams
will be "take home" tests.  On Tuesday, April
7, I will e-mail Exam 3 to you.  The test will
also be posted on the course website and a
link will also be put on Canvas.  You will
have until Tuesday, April 14 to finish the test.
When you have finished the test, you will
scan in your work and e-mail it to me at:

             jacobs@totcon.com

Let me know if you don't have the ability
to scan your work.

Carol Jacobs
