Answer to Problem 13.8.8EP

The amplitude, period, graph, equation of midline and vertical shift for the given function is determined.

Explanation of Solution

Given:

$y=\csc \left(\theta \right)-6$

Calculation:

The general form of the phase shift is given as,

  $\begin{array}{l}y=a\sin b\left(\theta -h\right)+k\\ y=a\cos b\left(\theta -h\right)+k\\ y=a\tan b\left(\theta -h\right)+k\end{array}$

If the value of h is greater than 0, then it shift towards the right

If the value of h is less than 0, then it shift towards the left.

If the value of k is greater than 0, then the shift is up.

If the value of k is less than 0, then the shift is down.

The vertical shift is -6

The equation of the mid line is,

$\begin{array}{c}y=k\\ y=-6\end{array}$

The graph is plotted as,

From the graph the amplitude is infinite.

Thus, the amplitude, period, graph, equation of midline and vertical shift for the given function is determined.
