Q. 5 - Precalculus Enhanced with Graphing Utilities

Question

It is easiest to graph $y=secx$ by first sketching the graph of _______ .

Step-by-Step Solution

Answer

It is easiest to graph $y=sec x$ by first sketching the graph of y = cos x.

Step 1. Given Information

The given function is $y=sec x$. We have to fill the blank.

Step 2. Filling the blank

As we know, the reciprocal of $sec x=\frac{1}{\cos x}$. So, the graph of secant function obtained by using this identity.

Thus, it is easiest to graph $y=secx$ by first sketching the graph of y = cos x.
