# Math 109 Homework Assignments - Winter 2005

• Homework assignments are due in class on the days indicated below and indicated on the class schedule.

• Future homework assignments will be posted at least one week in advance of the due date.
• ## General guidelines:

• Read and take notes on the chapter associated to the exercises before completing them. Reading math takes longer than reading fiction. Be prepared to spend some time with the section with pencil and paper nearby to take notes, write down questions, or fill in gaps in the steps given in the book.
• Write up neat solutions, not a collection of scrap work that resulted in the right answer. Be critical of your own proof writing skills: does your proof make sense? Is the logic sound?
• Most of the learning in this course will come from sitting and struggling with these problems, which often require a spark of inspiration. As a result, you MUST work on problem sets by yourself. Office hours for Robin and me are an oppurtunity to discuss problems you are having.
