Homework for Math 3110 Fall 2009

• Problem set 7: Section 4.5 #16 and #20, Section 5.1 #2 parts b, g, and h, Section 5.1 #24, Section 5.2 #6, Section 6.1 #7, Section 6.1 #13 parts b, d, and f, Section 6.1 #23, Section 6.2 #17 and #18
  Make sure you justify your answers. (For example, if the problem asks "Is R a commutative ring?" and the answer is "Yes", you must prove that R is a ring and that its multiplication is commutative.) You do not have to turn in all of these problems. You may choose 4 problems to turn in as problem set #7 and if you do any additional problems, I will count them as extra credit homework.
  Due: Friday, December 4^th.
• Problem set 6
  Due: Monday, November 16^th.
• Problem set 5: Section 3.2 #14 parts a and b, Section 3.2 #22, Section 4.1 #2 parts b, d, f, and h.
  Also, write these permutations as products of transpositions and determine whether they are even or odd (as in #8 and #4).
  Due: Monday, October 26^th.
• Problem set 4: Section 2.5 #26, Section 2.6 #5 parts b, d, and f, Section 2.6 #18, and Section 3.1 #47

  For the last problem: If you quote the result of another homework problem, you must turn in that problem as well.
