Step-by-step explanation:
The cosine function crosses the midline at x = pi/2 = 1.57, so point (pi/2, 0) will be on the graph. It has a peak at x=0. The vertical scale factor of 4 mean the peak is (0, 4).
Your sine tool will be able to plot the graph using these two points.

If you need a maximum or minimum that is to the right of the midline point, you can use the minimum at (pi, -4) = (3.14, -4).
