Chapter 4 - Graphs of the Circular Functions - Section 4.3 Graphs of the Tangent and Cotangent Functions - 4.3 Exercises - Page 171: 13 RECALL: (1) The period of the function $y=\tan{(bx)}$ is $\frac{\pi}{b}$. (2) The consecutive vertical asymptotes of the function $y=\tan{x}$ are $x=-\frac{\pi}{2}$ and $x=\frac{\pi}{2}$. Thus, with $b=4$, the period of the given function is $\frac{\pi}{4}$. Consecutive vertical asymptotes of the given function are $x=-\frac{\pi}{8}$ and $\frac{\pi}{8}$. This means that one period of the given function is in the interval $[-\frac{\pi}{8}, \frac{\pi}{8}]$. Dividing this interval into four equal parts give the key x-values: $-\frac{\pi}{16}, 0, \frac{\pi}{16}$. To graph the given function, perform the following steps: (1) Create a table of values for the given function using the key x-values listed above. (Refer to the attached image table below.) (2) Graph the consecutive vertical aymptotes. (3) Plot each point from the table then connect them using a smooth curve, making sure that the curves are asymptotic with the lines in Step (2) above. Refer to the graph in the answer part above.
