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?[br][br]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.[br][br]How does the value of "c" affect the graph? How is the value of "c" related to the midline of the graph?[br]How is the value of "a" related to the midline of the graph?
