Use the sliders to explore how the values of a, b, and c affect the shape of the sine and cosine graphs.

What happens when the value of "a" increases? What happens when the value of "a" is negative?
How does changing the value of "b" affect the shape of the graph. Specifically, describe how a b value that is less than 1 compares to one that is greater than 1.
How does the value of "c" affect the graph? How is the value of "c" related to the midline of the graph?
How is the value of "a" related to the midline of the graph?
