Use a graphing utility to graph each pair of functions in the same viewing rectangle. Use a viewing rectangle that shows the graphs for at least two periods. $$y=-2.5 \sin \frac{\pi}{3} x \text { and } y=-2.5 \csc \frac{\pi}{3} x$$
Determine the amplitude, period, and phase shift of each function. Then graph one period of the function. $$y=2 \cos (2 \pi x+8 \pi)$$
will help you prepare for the material covered in the next section.
$$\text { Solve: } \quad-\frac{\pi}{2}
Determine whether each statement makes sense or does not make sense, and explain your reasoning. A ride on a circular Ferris wheel is like riding sinusoidal graphs.
Without drawing a graph, describe the behavior of the basic cosine curve.
