No Bellwork today, students took Quiz #3.
After students turned in the quiz they were to work on a sheet asking them to plot points in order to explore the graph of y=Cosx. From the graph they were to find the Period, Amplitude and equation of the Midline and answer two questions about the graph of Cosx.

Bellwork reviewed graphing one period of a Sine Function and an SAT-like math question.
Hwk #9 is due today.
The remainder of the period we investigated how real-world data can me modeled with a Sine Function. Today’s classes were shorter than normal due to the late start.
Tomorrow is Quiz #3.

Bellwork gave students practice graphing a Sine function and writing the equation of a Sine graph.
Students were given a copy of the Review for Quiz #3. The quiz will be given next week. Exact day of the quiz is still to be determined.
Hwk #8 is due today.
The remainder of the period we began discussing Sec 13-7 – translations of Sine functions. Students first worked on an Calculator Exploration of the graph of y=Sin(x-h)+k. to discover how different values of h and k affect the graph of y=Sinx.
Hwk #9 was made available to the students.
Practice Sheet: Sec 13-7 (Sine only)
