Week 13:

Due Tuesday, November 13: Please note: the last two reading assignments should have been sections 12.1 and 12.2 (not 13.1 and 13.2, hopefully that was clear based on what we were working on in class). Read section 12.3 and do the practice problems. Hand in: Problems 8, 9 on page 555 and also: 1) Refer to the spirograph designs and problems 3, 4 on page 392, 393 of the activity manual. Describe a relationship among the number of dots in a cirlce, the "jump number N" where every Nth dot is connected by a petal, and the number of petals in a spirograph design. Your relationship should involve a LCM of some of the numbers. Explain why that relationship must always hold for any spirograph design that is made with dots in a circle by starting at one dot and connecting every Nth dot until you get back to the original dot. 2) Use the method of trial division to determine if the number 3719 is prime. Explain clearly how you know you can stop checking when you do.

Strips to cut out for LCM acitivity. Copy onto transparencies and cut apart.

Dot designs for spirograph activity

No office hours Wednesday since I'll be at a meeting in California.

Due Thursday, November 15: TEST on sequences (13.3) and series (13.4), functions (13.5 and 13.6, and reading on WebCT), especially linear and quadratic functions, and distinguishing linear relationships from non-linear ones, factors and multiples and GCF, LCM (sections 12.1, 12.2, but I won't ask about spirograph designs), prime numbers (12.3).

Week 14:

Due Tuesday, November 20: Read section 12.4 and 12.5 and do the practice problems. Hand in: Problem 4 on page 565 (be sure that you explain why your answer is true for all products of odd numbers even if you illustrate with a drawing for one particular case), and problems 9 and 11 on page 570.
