Forming study groups is permissible, but you must construct your solutions independently. By writing down my name, I
confirm that I strictly obey the academic ethic code when doing this problem set and my statement on attendance (above)
is correct. Please write down the names of
everyone
who you worked with on this problem set in the space above.
(i)
Seven questions, one for each day. There is one extra credit question, but the total score is capped by 100
points. Studies show that the learning process can be more effective and enjoyable if one starts reviewing
the material soon after class and does the exercises on a daily basis.
(ii) It’s critical to write out algebraic details and arguments. If you use math formulas or literature values, please
cite your source(s).
(iii) To make grading accurate and efficient, please answer questions in orders, please circle your answers,
and please include these 4 pages as the cover sheet for your solutions. Thank you.
(iv) If you have difficulties/questions, please find resources and assistance ASAP. There are 11 resources for
you (including 5 office hours per week)—please check Lecture Note #1.
(v) Academic ethics need to be strictly obeyed. No exceptions! Please refer to the syllabus.
