Fall 2023 EEL3003 HW6
Each "HW part 1" will require a PDF file for submission.
• File name) Your last name Your first name initial-HW#.PDF (example: KimG-HW2.PDF)
• Page 1) Your final numerical answers with units where applicable for all questions in the problem set.
• Subsequent pages) Your complete work (or meaningful attempts for partial credit if you did not
arrive at a final answer) for the assigned problem set. This is not scratch paper - neat writing is
expected.
Rubrics for Part 1 – Graded by Instructor/Peer Mentor
1.
60 points for turning in your solutions and answers to all problems on time, regardless of correctness.
2.
Clearly indicate which problem the work is for.
3.
No attempt or no meaningful attempt made on a problem: 0 points for the problem.
4.
This is not scratch paper. Writings must be legible and neatly written to show logical flow.
Illegible
assignments may not get credit – grader’s discretion. Make it easy for the graders to give credit.
5.
Late submissions will be penalized - see syllabus for policy.
