DEs book using Sage

[David Joyner]

Hi:

Marshall Hampton and I wrote a book on Differential
Equations using Sage, and 100% of the royalties go directly
to the Sage Foundation. It is out now. If you want a 25%
discount coupon (for your library or holiday gifts:-), just email
Marshall or me and we can send you the form with the code.

PS There is a draft version of the book here:

You should have included a link to buy the book, to encourage more
royalties to the Sage Foundation. :)

I found this link:
http://jhupbooks.press.jhu.edu/ecom/MasterServlet/GetItemDetailsHandler?iN=9781421406374&qty=1&source=2&viewMode=3&loggedIN=false&JavaScript=y

Is the front cover illustration a graph of the heat equation, with
initial temperature zero and the ends held fixed?

Also, if we get the discount, does the Sage Foundation get the same
royalties?

Yes, they do. But I think that you do have to pay for shipping if you buy
from JHUP (but not if you buy from amazon), so it might not be as much
savings as you might think.

Thanks Dan for adding the link!
