Question

Determine the amplitude or period as requested. Amplitude of y=3 cos 1 2

Answer 1

Answer:

The amplitude is 3

Step-by-step explanation:

Given

The right function is:

$y = 3 \cos(\frac{1}{2}x)$

Required

The amplitude

A sine function is represented as:

$y =A \cos(Bx + C) + D$

Where

$Amplitude = |A|$

By comparing:

$y = 3 \cos(\frac{1}{2}x)$ and $y =A \cos(Bx + C) + D$

$A= 3$

So:

$Amplitude = |3|$

$Amplitude = 3$

Hence, the amplitude is 3
