Class October 22, 2009

For the first thirty minutes of class, we took a quiz on our homework from 2.1 and 2.2. We then went over how to use the remainder theorem of a fourth degree function and how to easily find any value like f(3) with synthetic division. We also went over homework problems from last class, and this lead us into a bit of a review on long division with functions and synthetic division. We went back and found the zeroes of the function f(x) = x⁴ – 3x³ + 3x² – 3x + 2, which lead us into a review of the forms of complex numbers. From there, we also went over how to add, subtract, multiply, and divide complex numbers and how to find the complex conjugate. We also learned that projects were due by midnight on Friday, not Thursday.

Homework:

• Be sure your project is ready to be graded by Friday midnight.
• p. 167/17, 19, 21, 29, 33, 37-51 odd, 65, 71

Next Scribe: I'm not quite sure. Has anyone not been scribe yet?
