QUESTION 1

The first function is

$y = \sin(4x)$
A function of the form

$y = A \sin(Bx)$

has amplitude equal to

|A|

The amplitude of

$y = \sin(4x)$

is

QUESTION 2

The given function is

$y = 4 \cos(x)$

A trigonometric function of the form

$y = A \cos(Bx)$

also has an amplitude of

|A|

The amplitude of

$y = 4 \cos(x)$

is

QUESTION 3

The given trigonometric function is

$y = 3 \sin( (2)/(3) x)$

The amplitude of this trigonometric function is

QUESTION 4.

The given trigonometric function is

$y = 3 \cos(x)$

The amplitude of this cosine function is
