Week 4: Monday, February 5, 2007-Friday, February 9, 2007

**Day 9:** February 5, 2007

Class Cancelled.

The definition of fundamental theorem of algebra and DCquiz 3 are due on WebCT.

**Day 10:** February 7, 2007

Learned how to use the different aspects of WebCT, including how to submit assignments.

Took another quiz on how to find roots of a function in excel:

f(x)=(lnx-2)*(arctan(1+0.05x^{2})-pi/3)

**Day 11:** February 9, 2007

f(x)=x^2+6x+9=(x+3)^2

ROOTS: -3

f(x)=g(x)h(x)

if x* is a root of g(x)—>g(x*)=0

f(x*)=g(x*)h(x*)=0

( )( )( )

( )

asymptotes-tan/cot

fractions—>denominator=0

vertical asymptote-0 denominator

Assigned Assignment 1: Make your own f(x) in Excel for Monday
