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 2.1, pp. 36 - 37 **

Problems: 1, 5, 10

**Hint:** Problem #5 will take a while but its designed for you to understand
how the solution of the wave equation really describes physically what you expect to
see. Follow the book's hints carefully. For problem #10, factor the operator like
we did in class for the wave equation and then proceed as we did with the derivation of
D'Alembert's formula.
