Please retype the question before you answer it.  This homework should be no longer than a two pages per question including graphics.  Some answers may not require this much room. No references list is required.

After I grade this homework and return the work to ANY student, I will no longer accept late work from any other.  In the meantime, the usual 5% per day penalty will apply.

This assignment has a value of 7% of your trimester grade.

Finally, I photocopied the answers from my students last year, so if your answers match theirs... YOU LOSE.
