Chapter 13.5, Problem 10WE

To determine

The graph of the function.

Explanation of Solution

Given information:

The given function is $\sec x$

Calculations:

Here the given function is $\sec x=\frac{1}{\cos x}$ ..

If a function is of the form,

  $y=a\sin (bx+c)+d\text{ or, }y=a\cos (bx+c)+d$

Then the period of the function is

  $Period=\frac{2\pi }{b}$

  $\begin{array}{l}Here,\\ b=1\\ Therefore,\\ Period=\frac{2\pi }{1}=2\pi \end{array}$
