In class on 10/28, we started off by Ms. Sommariva showing us some some tips of how to use the N-spire calculator. There are certain functions we didn't know about that would be helpful for us to check our work. For example, we learned that we can type in a function and it will give the factors for us. Also, we completed a problem in the notes packet where we were trying to foil a expression to the 4th power. In this case, we could use Pascal's triangle. The N-spires allowed us check our work by typing expression in. 

Ms. Sommariva showed us a quick powerpoint about derivatives and tangent lines with graph examples. 

We received a new notes packet and went over the chapter 3 test requirements, definition of derivative at a point, formulas for difference quotients and an example. 

We ended class by completing a short exploration. We practiced the definition of derivatives at a point concept we learned in the notes packet. 

Our homework assigned (due on 10/30) was to complete HWK 3.2 pg 76 Q1-Q10 #3, 5, 9, 15, watch this video http://www.youtube.com/watch?v=TINfzxSnnIE, and use the backwards or symmetric difference quotient to find the derivative of x^4.
