## Instructions

- Please review the course syllabus and make sure that you understand the course policies for grading, late homework, and academic honesty.

- On the
*first page* of your solution write-up,
you *must* make explicit which problems are to be graded for
"regular credit", which problems are to be graded for "extra credit",
and which problems you did not attempt.
Please use a table something like the following

Problem | 01 | 02 | 03 | 04 |
05 | 06 | 07 | 08 | 09 | ... |

Credit | RC | RC | RC | EC | RC |
RC | NA | RC | RC | ... |

where "RC" is "regular credit", "EC" is "extra credit", and "NA"
is "not applicable" (not attempted). Failure to do so will result
in an arbitrary set of problems being graded for regular
credit, no problems being graded for extra credit, and a five percent
penalty assessment.

- You must also write down with whom you worked on the assignment. If this
changes from problem to problem, then you should write down this
information separately with each problem.

**Points:** Problems are worh 20 point each.
