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 3.4, pp. 76 - 78 **

Problems: 2, 3

**Note:** These problems should be solved using the method discussed in class:
Find a particular solution and the homogeneous solution to obtain the general solution
in terms of arbitrary functions f and g. Then solve for f and g using the initial conditions.

**Section 4.1, pp. 87 **
