7-13.

For each graph below, find two functions, one that uses sine and one that uses cosine, that will generate the graph. (Recall the 5-point method if you need help.)

  1. Periodic curve, x axis scaled from negative 3 pi to 3 pi, with 4 visible turning points, first at (negative 3 pi, comma negative 1), second at (negative pi, comma negative 7).

    The sine does not need a horizontal shift.
    The cosine needs to be shifted to the left.

  1. Periodic curve, x axis scaled from negative pi to pi, with 5 visible turning points, first at (negative pi, comma negative 1), second at (negative 1 half pi, comma 3).

    The cosine needs to be flipped.
