Use a vertical shift to graph one period of the function. $$y=\sin x+2$$
Determine whether each statement makes sense or does not make sense, and explain your reasoning. I used the graph of \(y=3 \cos 2 x\) to obtain the graph of \(y=3 \csc 2 x\)
Use a vertical shift to graph one period of the function. $$y=2 \cos \frac{1}{2} x+1$$
Solve: \(\quad \log _{2}(2 x+1)-\log _{2}(x-2)=1\) (Section 3.4, Example 7)
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. $$y=4 \cos \left(2 x-\frac{\pi}{6}\right) \text { and } y=4 \sec \left(2 x-\frac{\pi}{6}\right)$$
