Academic Honesty

Solutions you hand in for homework assignments must be your own work. Although you may discuss the general approach to solving a problem with other people, you should never discuss the solution in detail. You must not take any written notes away from such a discussion, and you should wait at least one hour after the discussion to write down anything about the homework questions. Also, you must list on the cover page of your solutions any people with whom you have discussed the problems. The solutions you hand in should be your own work. While writing them, you may look at the course textbook and your own lecture notes but no other outside sources.

Policy on e-mail from students on course materials, and questions

• I will not answer these e-mails in general.

  My time is spent more productively for the class's sake in different ways. For pertinent questions on the materials that students send me by e-mail, or for questions that many people seem to be having, I will try to address them in class.

• If you have a burning question I have not addressed, come see me during my office hours, or make an appointment if you need to.

  Many students do this already, and it is a good use of my time and theirs. I can usually answer a question a student asks in person in about a tenth the time than by an e-mail exchange. This is because writing it out takes much longer. Also, 80% of the questions people send me, I have no idea what they are asking. We would have to go back and forth by e-mail several times before I get to the bottom of it.

• For personal requests, such as "I cannot make the test", and so forth, e-mail is fine and I will attempt to answer you directly. However, I will NEVER answer emails sent from non-York accounts. I will NEVER answer emails which are not signed.

  So I do not mind students sending questions by e-mail. By all means, continue. Just do not necessarily expect a direct reply. I do read them, and mostly I try to address the issues and questions people have raised. If your question or issue remains after some time, let me know. For anyone who believes that I am purposely ignoring them, my apologies.

Policy on test regrading or reappraisal

Marking Scheme

There will be 10 homework assignments altogether, one per week.

If you miss one of the tests for a justified medical reason, the credit for that test will be transfered to the final exam. For example, if you miss one of the tests, your final exam's weight will be 50%.

Important Dates

Test 1 (in class)	Oct 2
Test 2 (in class)	Nov 1
Test 3 (in class)	Nov 29
Last class	Dec 4
Final Exam	Dec

Lecture slides

• The lecture slides are available online.

Textbook

• Kenneth H. Rosen. Discrete Mathematics and Its Applications, Eigth Edition. McGraw-Hill, 2018. Textbook web site.

  You do not need to buy the textbook in hardcopy. You should buy (in York Bookstore) Connect software that comes with an e-copy of the textbook. The codes for the software may not be available at the shelf of the bookstore; you may need to ask someone for help with getting them.

  When you register your account you must use your first and last name exactly as they are listed in YU records. Otherwise, you may get no credit for your homeworks.

When a section is assigned as reading, you should do a significant number of the associated exercises as practice. The homework excercises assigned below should be considered a starting point, but you should do more. (And if you have trouble with one particular exercise, do more similar ones.)

The back of the text contains answers for odd-numbered exercises. (In some cases the answers are very brief to save space; you would be expected to show more work.)

Homework assignments

There will be 10 homework assignments that must be done online. You have to register for Connect and submit the homeworks electronically. McGraw-Hill Connect is a learning tool that allows (among other things) automatic homework submission and evaluation.

Homework Policy

• There are no extensions for homework submissions
• If you believe that the solution provided by Connect is incorrect contact their support team
• Homeworks will not be regraded by hand unless the answer provided on Connect is incorrect
• If you still believe that your homework is graded unfairly for any reason, contact the TA responsible for this, Niloy Costa.
