Math.321.001 Differential Equations
Differential Equations 4th
by Paul Blanchard, Robert L. Devaney, and Glen R. Hall
As a means of controlling textbook
costs, this class will use the 4th Edition of the text named
above. A later edition is now available, so the 4th edition may
not be available from the publisher or in our
campus bookstore. As of May 2016, there are many new and used
copies of the 4th edition
available on the internet. However, if this edition is used in
other schools in the fall, the number of available copies may suddenly
drop. Therefore, it is highly recommended that students order a
copy as early as possible.

It is important that every student have a copy of the text by the first
day of class.
In addition to the text, students will need to have access to a suite
of software utilities called DE Tools.
If you purchase a new copy of the text, it may include an access card
for the software. If not, it appears that free access is
available directly from the publisher either as a zip
file to be installed or as an executable
file that you just put on your computer and open. Alternatively,
you may be able to find
the software elsewhere on the internet by searching for detools software. However, be
sure you get the right software. Some of the links that
turn up in a google search are for different differential equation tool
packages. Below is a screen shot of what appears when you start
the DE Tools program that we will be using.
