Part 1: You will explore the amplitude and period of the sine and cosine functions using the Guided Visualization found at Amplitude and Period of Sine and Cosine Functions.

Select the sine function and move one variable slider at a time and observe how the function changes. Select the reset button and investigate the cosine function.

Answer each of the following questions in your Initial Posting.

1. How does changing the value of A affect the graph of the sine and cosine function?

2. How does changing the value of A from positive to negative affect the graph of the sine and cosine function?

3. How does changing the value of B affect the sine and cosine functions?

Part 2: Go to a classmate's initial Part 1 posting. Read their responses to each of the 3 questions. Choose one response to comment on. Do you agree with their observations? If not, how do you differ? If you agree with their posting, rewrite it
