Homework

Daily Homework

Daily Homework will be assigned most class meetings and will typically be due the day of the next class session. The majority of the Daily Homework assignments are to be completed via WeBWorK, which is an online homework system. You should log in with your NAU credentials. In addition to the problems done online, you will also be asked to occasionally submit written work. With some exceptions, each exercise (WeBWork or written) from the Daily Homework will be worth a point. Unless a student has a documented excused absence, late Daily Homework will not be accepted. However, if necessary, the scores will be “curved.”

  • Daily Homework 1: Read the syllabus and write down 5 important items. Note: All of the test dates only count as one item. Turn in on your own paper at the beginning of class. This assignment is worth 5 points. (Due Wednesday, January 15)
  • Daily Homework 2: Accept the invitation to the class Google Group. I will be sending out invitations via email during the first couple days of classes. If you’d prefer to use an email address other than your NAU address, please let me know. This assignment is worth 5 points. (Due Friday, January 17)
  • Daily Homework 3: Stop by my office (Adel 119) and say hello. If I’m not there, slide a note under my door indicating that you stopped by (please put your first and last name on your note). This assignment is worth 5 points. (Due Friday, January 24)
  • Daily Homework 4: Complete the corresponding problems on WeBWorK. I made a short video that illustrates how to get started with WeBWorK. You can find the video here (YouTube). Note: There are some inconsistencies in this video due to the fact that I made it for my Fall 2012 class, but it should still be useful. (Due Wednesday, January 15 by 11PM)

Weekly Homework

The Weekly Homework will be graded for more than the correct answer. In particular, intermediate steps will be graded, as well as your ability to present a complete solution. Moreover, your write-ups should be neatly written and make proper use of mathematical notation. The problems for your Weekly Homework will cover a subset of material covered the previous week. This will provide you with an opportunity to reflect on previous material and to deepen your understanding. Sometimes the problems will be identical to problems that you have already done and sometimes they will be new. Each Weekly Homework assignment will be worth 10 points, regardless of the number of problems. You are allowed to submit up to two late Weekly Homework assignments with no penalty. Also, two of your lowest Weekly Homework scores will be dropped.
