The weekly homework assignment is in Webassign. Please note that WebAssign has some quirky rule for what can be entered where. If it is not accepting your answer check out: Answers that cannot be understood. Please follow the instructions for the problems that are given in the WebAssign environment. The links below are to public forms of the problem and may not include specialize WebAssign instructions.

You will be asked to do 3-5 challenging problems including estimations, explanations, essay questions, worked out problems, and even some challenging multiple choice questions. You are encouraged to work on these with friends. The Course Center is good space to work together and get feedback from a TA or Professor. CLICK FOR THE COURSE CENTER SCHEDULE.

You have to write up your solutions independently. Be careful: If two or more submitted answers are essentially identical, neither will receive credit. Online homework is due by Friday 5pm for both sections of the class.

Some problems (1-2 per week) will be written out on paper and will be due at the BEGINNING of the last class of the week each week. Paper homework will be scanned; therefore, the homework that you turn in on paper should meet the following guidelines: No staples, paper clips, dog ears, etc. At the top of EVERY PAGE, write your name, professor's name, section number, and "Page x of y" (e.g. "Page 2 of 5"). The quality of the presentation will be considered in the score as well as the quality of the solution.

Scores for webassign part of homework will be kept on webassign. Scores for the paper HW will be kept on canvas. It will not be possible to submit "show your work" attachments for webassign questions - you will have to explain your answers in the textboxes provided.

Here is a translation guide to the Universal Grading Codes that will be used in grading the homework, so that you can understand the comments that you get back on your homework.
