Safety Protocols

• For updated information on safety protocols in the classroom, see here, here and here.
• If you are feeling sick, do NOT come to class. Follow the quarantine/testing protocols in the above links.
• In class, everyone must be wearing a face mask, such as a cloth mask, surgical mask, or N95 mask. A plastic face shield is NOT a face mask. If you are not wearing a face mask, you should not be in the classroom.
• Eating food is NOT allowed during class.
• There is a zoom link posted on blackboard in case hybrid teaching (a classroom lecture with camera/microphone) becomes necessary.  The classroom is equipped with a camera/microphone, and I will try to get them working the first week of class.

Textbook: There is no required textbook. The first course resource is a freely available book:
Numerical Computing with Matlab by Cleve Moler (the inventor of Matlab), available online at: https://www.mathworks.com/moler/chapters.html. Some other textbooks that we will follow are:
Numerical Analysis: Mathematics of Scientific Computing, Kincaid and Cheney
Numerical Mathematics and Computing, Cheney and Kincaid

Software: Matlab is freely available as a download for USC students. You should download and install this software on your personal computer. Instructions for downloading and installing this software can be found here: https://software.usc.edu/matlab/. If you have not done so already, you should create a Mathworks account, associated to your USC email address (https://www.mathworks.com/login). Once you have installed Matlab, you should then install the NCM package (available at the bottom of this page: https://www.mathworks.com/moler/chapters.html). Once the NCM package is installed, you can access some of its features by just typing "ncmgui" in the Matlab command line.

Extra Credit Project: There will be an optional extra credit project, where students will create a computer program that plays a game (such as connect four or chess) in Matlab, and the top performers of a tournament will be awarded around 1% to 3% extra credit points for the course. The project would be due in the last week of class, and the "finals" of the tournament would occur in class during this time as well. Students can work in groups of up to three, and if a team wins some amount of extra credit, that credit will be split evenly among the participants. Also, copying any code from any online resource will result in automatic disqualification. Since I will be running the finals on a Microsoft Surface Tablet (without much memory or processing power), you are not allowed to use any functions from any extra Matlab toolboxes, other than those functions in the most basic installation of Matlab. More details are TBD.

Exam 1: Monday, September 26, 12PM-1250PM, WPH B26
Exam 2: Friday, November 5, 12PM-1250PM, WPH B26
Final Exam: TBD, Location TBD
Other Resources: An introduction to mathematical arguments, Michael Hutchings, An Introduction to Proofs, How to Write Mathematical Arguments

Email Policy:

• My email address for this course is stevenmheilman@gmail.com
• It is your responsibility to make sure you are receiving emails from stevenmheilman@gmail.com , and they are not being sent to your spam folder.
• Do NOT email me with questions that can be answered from this syllabus.

Exam Procedures: Students must bring their USCID cards to the midterms and to the final exam. Phones must be turned off. Cheating on an exam results in a score of zero on that exam. Exams can be regraded at most 15 days after the date of the exam. This policy extends to homeworks as well. All students are expected to be familiar with the USC Student Conduct Code. (See also here.)
Accessibility Services: If you are registered with accessibility services, I would be happy to discuss this at the beginning of the course. Any student requesting accommodations based on a disability is required to register with Accessibility Services (OSAS) each semester. A letter of verification for approved accommodations can be obtained from OSAS. Please be sure the letter is delivered to me as early in the semester as possible. OSAS is located in 301 STU and is open 8:30am-5:00pm, Monday through Friday.

Discrimination, sexual assault, and harassment are not tolerated by the university. You are encouraged to report any incidents to the Office of Equity and Diversity http://equity.usc.edu/ or to the Department of Public Safety http://capsnet.usc.edu/department/department-public-safety/online-forms/contact-us. This is important for the safety whole USC community. Another member of the university community - such as a friend, classmate, advisor, or faculty member - can help initiate the report, or can initiate the report on behalf of another person. The Center for Women and Men http://www.usc.edu/student-affairs/cwm/ provides 24/7 confidential support, and the sexual assault resource center webpage sarc@usc.edu describes reporting options and other resources.

Exam Resources: Some practice exams for a course similar to ours appear here.

Homework Policy:

• Homeworks are due at 10AM Thursdays, i.e. at the beginning of the first discussion session on Thursdays.
• Homeworks are submitted in blackboard, under the "Assignments" tab. You are allowed unlimited submission "attempts" for an assignment, but only the last submission will be graded. To avoid internet issues, I recommend making your first submission of an assignment well in advance of the deadline.
• Homeworks should be submitted as single PDF documents. One way to create a PDF document from paper homework assignments is the freely available Adode Scan App
• Late homework is not accepted.
• If you still want to turn in your homework late, then the number of minutes late divided by ten will be deducted from the homework score.  The exact deduction and rounding procedure is not guaranteed to be accurate.
• The lowest two homework scores will be dropped. This policy is meant to account for illnesses, emergencies, dropped internet connections, etc.
• You may not use the internet to try to find answers to homework problems.
• Do not submit homework via email.
• Collaboration on homeworks is allowed and encouraged.
• All homework assignments must be written by you, i.e. you cannot copy someone else`s solution verbatim.

Grading Policy:

• The final course grade is weighted as the larger of the following two schemes.
  • Scheme 1: class participation (3%), homework (22%), the first midterm (20%), the second midterm (20%), and the final (35%).
  • Scheme 2: class participation (3%), homework (22%), the largest midterm grade (30%), and the final (45%).
  The grade for the semester will be curved. However, I do not "curve down" since anyone who exceeds my expectations in the class by showing A-level performance on the exams and homeworks will receive an A for the class.
• If you cannot attend one of the exams, you must notify me within the first two weeks of the start of the quarter. Later requests for rescheduling will most likely be denied.
• Class participation is not the same as attendance.  I will never explicitly take attendance, but I will notice if someone is frequently absent.  Things that increase your class participation grade include: asking good questions, paying attention in class, showing up on time or early to class, etc. Things that decrease your class participation grade include: excessive talking or disruptions during class, frequent absences, excessive texting/smartphone usage in class, frequent tardiness, etc.
• You must take the final exam to pass the course.

Tentative Schedule: (This schedule may change slightly during the course.)

Advice on succeeding in a math class:

• Review the relevant course material before you come to lecture. Consider reviewing course material a week or two before the semester starts.
• When reading mathematics, use a pencil and paper to sketch the calculations that are performed by the author.
• Come to class with questions, so you can get more out of the lecture. Also, finish your homework at least two days before it is due, to alleviate deadline stress.
• Write a rough draft and a separate final draft for your homework. This procedure will help you catch mistakes.
• If you are having difficulty with the material or a particular homework problem, review Polya's Problem Solving Strategies, and come to office hours.
