Homework should be turned in at the BEGINNING OF CLASS.
All problem numbers refer to the Strauss book,
the required text for the course. Unless otherwise indicated,
all parts of a problem (a), (b), etc. should be completed.
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.

**Section 1.1, pp. 4 - 5 **

Problems: 2, 3, 4, 12

**Section 1.2, pp. 9 - 10 **

Problems: 1, 3, 5, 8

**Hint:** For #8, use the coordinate method to find the homogeneous solution.
Think back to inhomogeneous ODE's to find a particular solution. Be sure
to simplify your answer.
