Consider $\"\"$ .

$\"\"$

The two consecutive vertical asymptotes occur at $\"\"$ and $\"\"$ .

The vertical asymptotes are $\"\"$ and $\"\"$ in the interval $\"\"$ .

The vertical asymptotes are $\"\"$ and $\"\"$ in the interval $\"\"$ , where $\"\"$ is an odd integer.

$\"\"$

The interval $\"\"$ corresponds to one cycle of the graph.

Divide the interval $\"\"$ into four equal parts to produce the key points.

One fourth of part $\"\"$ .

The $\"\"$ - coordinates of the five key points are

Create the table listing the coordinates of key points like vertical asymptotes, $\"\"$ intercepts and Intermediate points.

$\"\"$

(1) First plot the asymptotes.The midpoint between two consecutive vertical asymptotes is an $\"\"$ - intercept of the graph.

(2) The period of the function $\"\"$ is the distance between two consecutive vertical asymptotes.

(3) Plot the points obtained in the table for one cycle.Finally, sketch one or two additional cycles to the left and right.
