I just wanted to let you guys know about the updated webwork problem set.
It has coverage for most of the book (not really chapter 5). It mostly comes
from the Open Problem Library, but quite a few new problems have been
written that aren't in OPL (yet), and many OPL problems were modified to
fit the book better. There are now a couple of options for using it:
1) Edfinity (easiest option, no install, student paid):
2) If you use a normal WeBWorK installation, then the problem set is at
You can simply upload it into webwork using the file manager (just into your
main templates directory, don't put it into any subdirectory) and it should
extract automatically. There will be a new diffyqs-webwork subdirectory.
In the directory there are set files that you can add as problem sets, or you
can point the library browser at the subdirectory.
Let me know if there are any issues, if anything is missing, etc...
