# How do you find the amplitude and period of #Arc Sec#?

##### 1 Answer

arcsec does not have a (meaningful) amplitude or period.

You seem to have confused arcsec with the direct trigonometric functions

#### Explanation:

arcsec(x) is an angle; typically its value is restricted to angles in the range

In terms of a unit circle arcsec(x) is the angle

Since the hypotenuse must be at least as long as any other side

The graph below demonstrates the arcsin relationship.

The vertical axis is the angle (in radians).

The horizontal axis is the arcsin argument value.
