HOMEWORK 2 ANSWERS Important note about homework: Please be sure you submit your homework questions in order, and you make it obvious which questions you are answering. In an effort to save paper, you do not need to submit the questions; you only need to submit your answers. Please be clear and concise when preparing your homework assignment.

If you put your homework in Say Young’s mailbox, send him an e-mail immediately afterwards to notify him of such and to document when you turned in your homework. It is your responsibility to turn your homework in to Say Young. Thus, other TAs will not relay your homework to him. Important note about early homework: If you anticipate not being able to turn in your homework before lecture on the day that it is due, you may turn your homework in early.
