Chapter 7: Q 2. (page 457)

The graph of y=secxis one-to-one on the

interval [0,蟺2)and on the interval(蟺2,蟺].

Short Answer

Expert verified

The given statement: The graph of y=secxis one-to-one on the

interval [0,蟺2)and on the interval(蟺2,蟺]is true.

Step by step solution

01

 Step 1. Given information

The functiony=secxis one-to-one on the

interval[0,蟺2)and on the interval(蟺2,蟺].

02

Step 2. To find value of Sec x.

Secx=1Cosx

Suppose Cosx=0then xwould be multiple of 蟺2.

That is, if x=蟺2then

Cosx=Cos(蟺2)Cosx=0

and

Secx=1CosxSecx=1Cos蟺2Secx=10=undefined

03

Step 3. Graph of the functiony=secx.

From graph we observe that the given statement is true.
