Exams in weeks 5 and 11 (flexible dates).

All homework problems must be turned in one week after they have been assigned. Furthermore, homework is due at the beginning of class. Late homework will not be accepted.
Exams will be closed book and closed notes. One 8.5 x 11 sheet of equations will be permitted. No example problems may be on this sheet.
Only neatly written homework and exam problems will be graded. A correct answer without a correct outline of the solution will not carry any grade.
