Homework should be turned in at the BEGINNING OF CLASS.
All problem numbers refer to the Hughes-Hallett, Gleason, McCallum, et al. book,
the required text for the course. You should write up solutions neatly to all problems,
making sure to SHOW ALL YOUR WORK.
A nonempty subset will be graded. You are strongly encouraged to work
on these problems with other classmates, although the solutions you turn in
should be YOUR OWN WORK.

** Important: ** Please list the names of any students or faculty who you worked with
on the assignment.

**Hint:** Remember, the key point for this section is that you can check
whether a function is a solution for the differential equation by plugging
it into both sides of the equation.
