Unformatted text preview: M4080 Fall 2009 Assignment 3 Due Thursday, September 17 You should have read and understood sections 3.3, 3.4, and 3.5 before completing this assignment. You must show sufﬁcient work in order to receive full credit for a- problem. Please write legibly and label the problems clearly. Circle your answers when appropriate. Multiple papers must be stapled together. Write your name and the time of your discussion section on each page. You may use calculators for arithmetic. I strongly discourage you from using a cal- culator to do any algebraic simpliﬁcation, etc., since you will not be allowed to use one on the exams. Feel free to discuss these problems with your classmates. However, each student must write up his or her own solution. _ 2 (1 cosac) , \$750 1.
