RECALL: The function $y=a\cdot \sin{x}$ has: period = $2\pi$ amplitude = $|a|$ The given function has $a=3$ the function has: period = $2\pi$ amplitude = $|3|=3$ Thus, one period of the given function is in the interval $[0, 2\pi]$. Divide this interval onto four equal parts to get the key x-values $0, \frac{\pi}{2}, \pi, \frac{3\pi}{2}, 2\pi$. To graph the given function, perform the following steps: (1) Create a table of values using the key x-values listed above. (Refer to the table below.) (2) Plot each point from the table then connect them using a sinusoidal curve. (Refer to the graph in the answer part above.)
